[Solved] Unable to run on android using Qt 5.4
-
Hi all
In short my situation: I have a code that using the old Qt 5.3.2 was able to run into android. Same code, once moved to latest Qt 5.4 ( and latest version of Qt Creator too) doesn't work anymore. I tried all the possible combination but without success. Before report the error please note I'm still using Ant for apk packaging since if I select Gradle the tool attept to download the gradle zip file but I'm through a proxy and the download fail.Currently the target of my app is android-15 but when I execute the following error show up in the console:

Hi
Finally found the problem. In the creation of AndroidManifest.xlm file I didn't set any name into Application -> Run field. This have the result to generate the xml with the following settings empty:
@<meta-data android:name="android.app.lib_name" android:value=""/>@
and this cause the error (that was not very clear). Here is needed t set the application name to start.

As you can read from my first posts here this error (java.lang.ClassNotFoundException: android.graphics.drawable.RippleDrawable) it isn't critical since it happen using standard Qt examples too. Basically RippleDrawableis a class introduced in android 5, in all older version this error came up but the app start equally than is not the problem.
