ANR while SQLiteDatabase.loadLibs

[arvifox]

Expected Behavior

Actual Behavior

I get an ANR during SQLiteDatabase.loadLibs(context).
I use ContentProvider to initialize the database and sqlcipher because my application works in background.
I call the loadLibs() method in the ContentProvider.
The ANR happens only on Samsung S20, S20+, S20 Ultra on Andoroid 10 (OneUI 2.5) and only after reboot of a phone.
If user starts the application manually everything works well.
Also I use ndk.abiFilters 'armeabi-v7a', 'arm64-v8a'
Please help me

Steps to Reproduce

SQLCipher version (can be identified by executing PRAGMA cipher_version;):

SQLCipher for Android version: 4.4.0

Hi @arvifox

If you remove your ABI filter, does the same behavior occur?

[arvifox]

Hi @developernotes
The same behavior occurs.
In logfile I see these lines about 2 minutes after SQLiteDatabase.loadLibs is called.

Hello @arvifox

The next step is to isolate your application and logic from the library to verify that integration usage isn't the cause. Would you try recreating the issue in isolation within the SQLCipher for Android test suite. We would be happy to review a reproduction case.

Hello @developernotes
I tested within test suite.

Behaviiour Test suite Passed: 114, Failed: 0
Support Test suit: Passed: 99, Failed: 0

Then I created new ContentProvider, just copypasted from ZeteticContentProvider and added

Log.i("foxxx", "content provider create");
SQLiteDatabase.loadLibs(getContext().getApplicationContext());
Log.i("foxxx", "content provider loadlibs done");

to OnCreate method.
everything works well if a user start application manually.
but if Contentprovider starts after reboot of a phone I dont see content provider loadlibs done line in logcat, and then I get ANR.
it is reproducible only on samsung s20 with OneUI 2.5 launcher.
BTW today morning I installed android 11 on my Pixel 4. Everything works well on android 11.

Hi @arvifox

Since you are only able to reproduce it on a Samsung s20, would you modify the content provider in the test suite to call this before you call loadLibs(...). I'm curious if you see consistent behavior.

try {
  Log.i("foxxx", "before loadLibrary");
  System.loadLibrary("sqlcipher");
  Log.i("foxxx", "after loadLibrary");
} catch (Throwable ex){
  Log.e("foxxx", "exception loading SQLCipher", ex);
}

Hi @developernotes ,
I'm a colleague of @arvifox .

I tried your last approach and face the same issue. App stucks at System.loadLibrary("sqlcipher");.
If I try to load another library, this one works

@Override
protected Configuration getConfiguration() {
Log.i("foxxx", "doInit# init securelib start...");
 try {
    Log.i("foxxx", "before loadLibrary gdk");
    System.loadLibrary("gdk");
    Log.i("foxxx", "after loadLibrary gdk");
    Log.i("foxxx", "before loadLibrary sqlcipher");
    System.loadLibrary("sqlcipher");
    Log.i("foxxx", "after loadLibrary sqlcipher");
} catch (Throwable ex){
     Log.e("foxxx", "exception loading libraries", ex);
}

We are facing the same issue with the ANR in the exact same phones mentioned here? Any updates on this one @developernotes ?

[rsamoilenko]

We are facing the same issue on the same set of devices and only after system reboot. Might this be due to android:directBootAware="true" on our BroadcastReceiver that is triggered after reboot with BOOT_COMPLETED intent?
