Android - restart when hitting the power button

SDL Development
1

Hi.

I’m running out of ideas for this one:

The app is restarting automatically when I hit the power button on my S3
(this does not happen on my other devices).

V/SDL (25874): onPause()
V/SDL (25874): nativePause()
D/SensorManager(25874): unregisterListener:: Listener=
org.libsdl.app.SDLSurface at 42913af0
V/SDL (25874): onDestroy()
D/dalvikvm(27512): Trying to load lib
/data/data/org.caveexpress/lib/libSDL2.so 0x428fabe8
D/dalvikvm(27512): Added shared lib

D/dalvikvm(27512): Added shared lib

D/dalvikvm(27512): No JNI_OnLoad found in
/data/data/org.caveexpress/lib/libSDL2_image.so 0x428fabe8, skipping init

/data/data/org.caveexpress/lib/libSDL2_mixer.so 0x428fabe8
D/dalvikvm(27512): No JNI_OnLoad found in
/data/data/org.caveexpress/lib/libSDL2_mixer.so 0x428fabe8, skipping init
D/dalvikvm(27512): Trying to load lib

D/dalvikvm(27512): Added shared lib

D/dalvikvm(27512): No JNI_OnLoad found in
/data/data/org.caveexpress/lib/libSDL2_net.so 0x428fabe8, skipping init
V/SDL (27512): onResume()
V/SDL (27512): onPause()
V/SDL (27512): surfaceCreated()
V/SDL (27512): surfaceChanged()

This strange behaviour leads to a lock and black screen on my phone
while the SDL mainloop is running.

Notice that onPause is triggered by hitting the power button and no
other action is done in between the logs you see there.

Any idea why this happens? Anyone with the same problems? And maybe even
better - anyone with a suggestion how to solve this issue?

If you get sent a onDestroy message when you press the power button, it’s
most likely something missing in the AndroidManifest.xml, specifically in
the android:configChanges property. Are you using the default SDL project,
any customizations?–

Hi

I’m using a modified manifest. I will check for diffs - thanks for the
hint (would have never guessed that)
