android os从版本9升级到10后无法获取设备ID

Question

I have problem on getting unique device id: Settings.Secure.getString(this.contentResolver, Settings.Secure.ANDROID_ID)

• On version below and equal version 9, I can get device id.
• Onversion 9, I cannot get device id.

Answer 1

You need Manifest.permission.READ_PHONE_STATE

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
     ActivityCompat.requestPermissions(getApplicationContext(), new String[]
     {Manifest.permission.READ_PHONE_STATE}, RequestCode);
}
else
{
    // doesn't need permission 
}

AndroidManifest.xml

<uses-permission android:name="android.permission.READ_PHONE_STATE" />   

Answer 2

You can use this code to get device ID:

private String deviceID;
deviceID=Settings.Secure.getString(getContentResolver(),
                                                   Settings.Secure.ANDROID_ID);
