A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x7d400300 in tid 27503 when adding mircroblink license file

Question

So I have a project that contain a microblink library which is I need to declare it in MainActivity, here what it looks like

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ButterKnife.bind(this);


    /** Set the License from the file*/
    MicroblinkSDK.setLicenseFile("this is my license file", this);

    

}

Then I run the program and getting error fatal signal, but when the declaration code from microblink I remove it can work as usual. I've tried search for the solution and there it said to adding this

android:hardwareAccelerated="false"

in the manifest file but failed and the error doesn't change. Some help would be so nice!

here is the debug log

Firstly, from the log, I can see that you are using version 4.7, which is an old version of BlinkID which came out in February 2019. I suggest trying to implement the latest version (5.9), which you can download here: https://github.com/BlinkID/blinkid-android/releases/tag/v5.9.0

Also, regarding the license key method, the recommendation is to implement it in the way that you extend the Android Application class and set the license in the onCreate callback like this:

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        MicroblinkSDK.setLicenseFile("path/to/license/file/within/assets/dir", this);
    }
}
