Please help me,

My app open a white view and close after 20 seconds...

in the logcat's Android Studio list this errors:

'libEGL' pre_cache appList:com.miui.weather2,com.android.settings,com.android.thememanager,com.mi.android.globalFileexplorer,com.miui.gallery,com.miui.notes,com.miui.player,com.miui.calculator,com.miui.videoplayer,com.miui.securitycenter

'libc' A Fatal signal 5 (SIGTRAP), code 1 (TRAP_BRKPT), fault addr 0x70c1081b68 in tid 15641 (my app), pid 15641 (my app)

Which ionic files should I change to fix these errors?

Thanks for the help!
