Unfortunately, Package Installer has stopped

"Unfortunately, Package installer has stopped working" pops up when I try to install my app on my phone via bar code or hard wired, it didn't do this before and it doesn't do this for my husbands phone.. Has anyone come across this before and know what to do about it? It started doing this for my phone after I changed the name.. But again, it works fine for my husbands phone..

its only coming across as 1.96MB but in my husbands phone its 5.96MB... What is going on here??

probably no space anymore on your device?

Please help for creating a search bar

How do you create a search bar that can link you to a web site?

see here Using the Activity Starter

Launch a Web search

To launch a Web search, use an ActivityStarter with the WEB_SEARCH action. The user’s phone will display a menu asking what kind of search to perform:

Action: android.intent.action.WEB_SEARCH

Empty String

Anyone know what this means...

You should only use true or false operation checked

I have 7 other screens that I are done the same as this screen and they work, and I did not do them like you suggest... I will try to see if I spelled something wrong or made a mistake somewhere..

as Boban already suggested: what about using a logic block true or false as you need it?

Fusion Tables Problem

Hi everyone, I'm using FusionTables for my aplications in App Inventor and it normarly works showing the table in the WebViewer just fine. But now any of my tables are showing in the aplications I was using. For programs with fusion tables I use the link "Publish Send a link in email or IM"

I want to know if its just me or if there is something with fusion tables, thanks

But now any of my tables are showing in the aplications I was using.

what does that mean exactly? can you elaborate?

For programs with fusion tables I use the link "Publish Send a link in email or IM"

this is correct

I have some aplications that uses WebViewer to see a fusion table, Normaly it works i could see the table by using the WebViewer but now is blank. I post one of the links I'm using for the table.

https://www.google.com/fusiontables/embedviz?viz=GVIZ&t=TABLE&q=select+col0%2C+col1%2C+col2+from+1PU5FtW5aWeN_ZjMQxH-5VUp3OWuYbo5rKJdzXeeC&containerId=googft-gviz-canvas

works fine for me, see attached example project

jorge.aia

Thanks I think that the problem is the device where I'm using the aplications because I've used the jorge.aia program and is in blank.The device was showing the tables before, but now is blank. I'll try on another device or in the emulator, thanks

USB Debugging switch from App?

Is it possible to control from the App the USB debugging function (on/off)? I can activate it manually via Android settings... but I want to create a button in my app to control it.

Maybe it is not my business, but why would you want to do that?

see also this stackoverflow question http://stackoverflow.com/q/18782546/1545993

✱✱✱✱✱✱✱

If you use an Android phone and you’ve searched forums for solutions to problems, you’ve probably heard the term “USB Debugging” every once in a while. You may even have seen it while looking through your phone’s settings. It sounds like a high-tech option, but it really isn’t; it’s quite simple and useful.

One beauty of Android is that it has a lot of built-in features, many of which are advanced. If you want to supercharge your phone with mods and whatnot, you can; if you want to use it just as it was out of the box, you can ignore the advanced stuff. USB Debugging is a feature that all users can benefit from, though, so you should know what it does and when to use it.

What Is USB Debugging Mode?

USB Debugging Mode is a mode that can be enabled in Android after connecting the device directly to a computer with a USB cable. The primary function of this mode is to facilitate a connection between an Android device and a computer with Android SDK (software development kit). As the name might suggest, Android SDK is a software suite that’s designed to aid in the development of Android apps.

Ever wondered how a programmer creates apps on the Android? They definitely don’t code them straight on the phone device! That would be nightmarish at best. Instead, they utilize the environment of the Android SDK to code apps on a computer, use USB Debugging Mode to transfer those apps to a device for testing.

But, again, here’s the takeaway: USB Debugging Mode establishes a direct connection between an Android device and a computer and readies it for deeper-level actions. That’s the important part.

In some versions of Android, the USB Debugging Mode feature may be called Developer Mode. With such a name, it can be easy (and reasonable) to think that you’ll never need to deal with this aspect of Android if you never plan on developing anything. That’s not exactly true.

Why Is USB Debugging Mode Important?

USB Debugging grants you a level of access to your device. This level of access is important when you need system-level clearance, such as when coding a new app. However, there are a few non-development-related benefits from this new level of access that can give you much more freedom of control over your device.

For example, with Android SDK, you gain direct access to your phone through your computer and that allows you to do things you normally couldn’t, like snag instant screenshots of your device or run terminal commands with ADB. These terminal commands can help you restore a bricked phone–a useful tool for any adventurous Android owner. Without it, you’d have to get a replacement phone.6 Ways To Take Screenshots On Android 6 Ways To Take Screenshots On AndroidThis is how to take a screenshot on Android -- no matter what version you're running.READ MORE

USB Debugging is also necessary if you ever want to root your Android device. Before an app like One-Click Root can dig into your system and deliver the exploit that roots the device, USB Debugging is necessary to allow that function in the first place.How To Root Your Android Phone With SuperOneClick How To Root Your Android Phone With SuperOneClickREAD MORE

Yes, the original intention for USB Debugging Mode was only meant for developers who needed to copy data between their computers and Android devices, to install apps on the phone without notifications, and to read log data off the phone. But even if you aren’t a developer, you’ll probably run into a few apps that require USB Debugging Mode to function properly, so this mode does affect you and you should know about it.

What You Need to Know About USB Debugging Mode

By this point, you may have noticed that USB Debugging isn’t used all too frequently. You’re right. This feature of Android isn’t something that you take advantage of on a daily basis unless you’re coding an app. However, when it does come in handy, it really saves you a lot of time, effort, and even money.

Therefore, it’s best to keep USB Debugging Mode disabled and only enable it when you really need it. When running an app, for example, it’ll let you know if it needs you to enable the mode before it can do anything. When that happens, you can enable it, let the app do its thing, then disable it again. Few apps will require your phone to constantly be in debugging mode.

Lastly, starting with Android 4.2, access to the USB Debugging Mode option has been hidden by default. I’m not entirely sure why the development team thought that move was necessary, but fortunately it’s not too much of a pain to get it visible again. Read How to Enable USB Debugging on Android 4.2 if you need to know how.

Conclusion

Just know that USB Debugging is not a super-high-tech feature that you need to be afraid of. Think of it as yet another tool that gives you full control over your device. This kind of power does invite abuse, though, so keep it disabled at all times and only enable it when you know you need it and you’ll be fine.

If you have any questions about USB Debugging, please ask in the comments. I’ll try my best to answer them.

App inventor for not loading my project

Is there a problem with app inventor cause I keep getting errors and it doens't load my project.

It keeps on saying internal error want to report.

Maybe try again in another browser, or clear the cache of your browser.
Did your project load earlier?
What else are the circumstances of your problem?

--

Cleared Cache changed browsers but no sulution

is this a large project? how many screens? how many components? loads of assets like images, audio, video files?

you always can try to import your latest backup and restart working from there

size limit

is there limited download file size in app inventor .... i make app more than 10mb ..what should i do ???

Please use the search box on top of this forum page to search before starting a thread. There's a lot of user who asked these common questions before and the answers are always the same.

These are the results of searching for "size limit"

thank you ^_^

there is an error loading!

There is an error load it say the following on the top of the screen when I load any of my projects and when I go to the block section:

The blocks area did not load properly. Changes to the blocks for screen 4851932204367872_Screen1 will not be saved.

is this a large project? how many screens? how many components? loads of assets like images, audio, video files?

Which browser and OS are you using?

Microsoft Edge and Internet Explorer browsers are not supported.

A Paleta do App (The App Palette)

The Paw is gone and I do not know how to restore it to bring it back! No blocks are available for me

my guess is, some shadow zombies have eaten them ;-)

try another browser instead

Try [Shift][F5] to refresh the browser.

Sometimes the palettes don't initially display properly upon loading in the Designer and Blocks viewer.

Publishing Apps to Google Play (App Inventor 2)

Uploading Apps to Google Play

Applications built with App Inventor can be uploaded to Google Play!

Version Your App

Every app you publish must have a VersionCode and a VersionName. You can set these in the designer under the properties panel for the Screen1 component.

VersionCode is an integer value that will not be visible to Google Play Store users. It is used by other apps to check if your app has been upgraded or downgraded. It defaults to 1 and should be increased by one with every successive change whether it is a major change or a minor change.

VersionName is a String which can be anything you would like. It is defaulted to 1.0. A common structure is a decimal number which is increased by 1 for every major change and 0.1 for every minor change. For example, an initial VersionName could be 1.0 which can be updated to 1.1 after a small change and 2.0 after a larger change.

You will need to increase the VersionCode and change the VersionName of your application when you upload a new version to the Play Store.

Download `.apk`

Once you are done making your app, you can download your Android .apk file as follows:

1. Navigate to the home screen of the app you want to download in App Inventor

2. Click the dropdown labled “Package for phone”

3. Click “Download to This Computer”

This will prompt you to save the application somewhere. Once you have the .apk downloaded, you are ready to begin the publishing process.

Publish Your App

You can now go to Google Play Publishing Home and follow the steps to publish your app to Google Play.

For more details, you may want to start with Introduction to Publishing on Google Play and Google Support on Uploading to Google Play.

A Word about Backups

Once you publish your application in the Google Play Store, other people will now be depending upon you to fix bugs and otherwise maintain your application. It is therefore very important that you backup your application's source code. To do this, click on "Project-->My Projects", check the box next to the name of your project and then select "Project-->Export selected project (.aia) to my computer." This will download a zip file which contains your projects source code. Store it in a safe place!

MIT and Google, which operate the App Engine service on which MIT App Inventor relies, make best efforts to ensure that MIT App Inventor does not lose projects. HOWEVER WE CAN OFFER NO GUARANTEE THAT DATA (LIKE YOUR PROJECTS) WILL NEVER BE LOST. IT IS IMPERATIVE THAT YOU MAKE YOUR OWN BACKUPS!

A Word about keystores:

During the .apk building process your application is signed with a digital private key which is associated with your account. Whenever you build a new version this same key is used to sign the new version. When an android phone has an application installed on it, it remembers the key that was used to sign it. In order to install an updated version of an application, the new application must be signed by the same key. It is therefore important that you not lose this key!

Your private digital key is stored in a keystore file. Normally the MIT App Inventor server will create this file when needed and store it for you so you do not need to worry about it. Although we do not anticipate losing your keystore file, we recommend that you back it up. From the designer under the "Projects" menu there is a choice labeled "Export Keystore". Select this option. This will download your keystore file to your local computer. Save it in a safe place. It should not be publicly readable as your private digital key is a secret which should not be shared.

If you move your project to another App Inventor server, you will want to upload your keystore to that server (you will see that under "Projects" there is a "Import Keystore" option as well). You only need to do this if you are publishing .apk files to Google Play or if you intend to share your application with other people in general.

IF YOUR keyfile IS LOST OR DELETED IT CANNOT BE RECOVERED. If you were to lose your project's source code, you could always re-enter it from scratch (this may be a lot of work, but is something you can do). NEITHER YOU NOR MIT CAN RECOVER A LOST keyfile. NO AMOUNT OF EFFORT WILL RECOVER IT, SO BE SURE TO BACK IT UP!!!
