Android Question App stops working android 4.4 AppCompat

rscheel · Oct 1, 2016

As the title says my application lets not start stops working when you open it, this only happens in android from android 4.4 down, android 5 up works correctly, I can realize that the following line of code causes the problem.

B4X:

#Extends: android.support.v7.app.AppCompatActivity

thanks.

You should post the error message from the logs.

Make sure to use the latest version of AppCompat library.

rscheel · Oct 2, 2016

I'm using the latest version of appcompat and the latest version of B4A, I can not send the log as the application falls to run and shows nothing in the log.

If you want you can send the code of the application by private message.

You should switch to USB debug mode and monitor the unfiltered logs.

In both cases does not provide any log.

This is the direct link to the application in play store in android 5 up working properly.

There must be an error message in the logs if the app crashes.

Have you tried to run the example: https://www.b4x.com/android/forum/t...le-with-older-android-versions.48423/#content ?

If I tried the example and the same thing happens, the application falls to start and shows nothing in the log.

Can you post the unfiltered logs? Make sure to connect in USB debug mode.

Dear this is what shows the log

B4X:

LogCat connected to: 64b497ca
--------- beginning of /dev/log/system
--------- beginning of /dev/log/main

And I share this video.

Erel · Oct 5, 2016

Uncheck the Filter option and run it again.

rscheel · Oct 5, 2016

It leaves a lot of text but nothing marked in red, and nothing appears identifying the problem, the extent of the log I can not publish.

I have reviewed and I found this referred to appcompat

Are you using B4A v6+ ?

Try to update the Android SDK build tools and support repository.

I'm using the latest version of B4A 6.30 but with the v6 same happens the same, I'm using the latest version of sdk and repositories, even update the jdk, and the same thing happens, not if someone else will have this same problem or I'll be just me.

And I'm using the version v3.30 AppCompat.

Read the AppCompat library setup instructions and be sure you follow step 3. Don't miss the part in bold and red. (Guess why it is bold and red)

@Erel You said that in latest B4A versions 23.0.3 Build tools will be preferred. This seems not to be completely true since this error was reported many times in the past. Every time the solution was to deinstall all Build tools except 23.0.3. It seems that an older aapt version is used when it is installed.

Erel · Oct 5, 2016

Have you seen step #3 in the tutorial: https://www.b4x.com/android/forum/t...le-with-older-android-versions.48423/#content ?

Erel · Oct 5, 2016

v23.x is preferred.

Dear thank you very much for your reply, that part had not read, as I have long using AppCompat and had never had problems with this, sometimes you omit some instructions are simple but cause a big problem, thanks for everything and regreted caused.

For AppCompat it is important to read the setup instructions for every release. Google sometimes changes important things in the support libraries (like in this case they introduced vector drawables which need special Build Tools version to get them work on Android <5.0) and I try to keep the installation instructions up to date as good as possible.

Unfortunately I can't read all questions in the questions forum anymore so I sometimes miss AppCompat related questions.
