Invalid ELF file

if I run my application on Android I always get this error and the application crashes immediately:

What could be the root cause of the error? The ffmpeg libraries I use are from here. What does the error "invalid ELF file" mean?

The file /lib/arm64/libswscale.so is corrupt. In particular, it has a PT_LOAD segment with offset that is past the end of the file (file size is 0x40910) and has 0 length.
One way the file may have become corrupt is if you did an FTP transfer and forgot to set binary mode. (Of course there are numerous other ways, such as decompressing the archive and running out of disk space.)
Your best bet is to re-extract the archive, check the length and md5sum of the file, and use scp or something other than ASCII FTP transfer, then verify that the md5sum is still the same on the target device.

Android release APK fails immediately on launch on mobile device

The Android release APK crashes on launch when I install it on mobile device. It works fine on Android Emulator. Also, debug builds work fine on Emulator.
I’ve tried the methods in the below link suggested by #bhardman, #gderaco + #sacchykhedkar and #alvelig so far with no success.

You open the app on your mobile device. And the app opens.
Actual behaviour:
App fails to launch on Android phone. Error message:

Error messages (from logs.txt file generated from the Android phone):
I can't tell which lines are relevant. So I searched with the app name "sampleapp".

App closes without any error when I send BOOT_COMPLETE broadcast from ADB Shell

I have a boot complete broadcast receiver which was not being called when the phone restarted, so I removed everything from onReceive method, added a log statement and used ADB shell to send BOOT_COMPLETE broadcasts, now the app just closes down without any message when I send the broadcast and the status of the app goes to DEAD in the logcat package dropdown.
I have the following permission defined in my Manifest file:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Here is how I'm registering my receiver:
<receiver
android:name=".BootCompleteBroadcastReceiver"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
I have tried without the android:exported="true" tag.
I am doing nothing in the onReceive method, I just have a log statement which is not being printed.
Here's the logcat, the apps seems to be force closed somehow, no error whatsoever:

It seems that crash is somehow related to WiFi, but Android emulator shouldn't have WiFi support anyway. What could be the issue here?

I managed to fix it myself. The problem seems to be due to com.android.settings.wfd.WifiDisplaySettings.isAvailable reporting that WiFi is available, while wifip2p service is absent. I went to WifiDisplaySettings.java:216 and replaced this check with false, so it won't try to locate the service. Now Settings can be opened properly.

Alter your WifiDisplaySettings.java in
/YoutAospRoot/packages/apps/Settings/src/com/android/settings/wfd/WifiDisplaySettings.java
Change the code snippet
public static boolean isAvailable(Context context) {
return context.getSystemService(Context.DISPLAY_SERVICE) != null
&& context.getSystemService(Context.WIFI_P2P_SERVICE) != null;
}
To
public static boolean isAvailable(Context context) {
return false;
}
Then
make systemimage

Maybe this can help too. I noticed that the Settings app is not crashing when building an clean Android 8 with lunch aosp_x86-userdebug instead of lunch aosp_x86-eng.

All Unity APKS crash in an Android Phone

I build an android apps about naked 3d display with Unity. I run it in 4 android phones, it runs well. But when I run it in a naked 3d mobile phone, the apps crashed. And all the apps generated with Unity can't run in this phone, even the simplest scene in Unity. But the apps generated by Android Studio, it can run well. It really confused me!
Here is the Log when I run the app in this phone, the phone is PPTV KING 7S.
