android-7.0-nougat

Users can purchase a "Pro" version of my app. When they do, I store and verify their purchase as follows. Combine the user's UUID and another unique string. The resulting string is then encrypted using a static seed. I do this using SecureRandom.getInstance("SHA1PRNG", "Crypto") - This is the problem! The resulting encrypted string is then the "unlock code". Therefore, I always know the expected unique unlock code value for the user. When the user purchases "Pro", I store the "unlock code" in the database. I check to see whether the user has "Pro" by seeing if the stored "unlock code" in the

In Android 7 Nougat, user installed certificate goes to "User credentials" instead of "Trusted credentials"(which consists of system credential & user credential). I used to access "Trusted credentials" by: KeyStore keystore = KeyStore.getInstance("AndroidCAStore"); through the above code I can then access system & user trusted credentials. But now, in Android 7, user installed certificate goes to a separate place called "User credentials" under Settings --> Security --> User credentials . My question is how can I programmatically list the credentials inside User credentials in Android 7? To

In Nougat, this function is not working. String path = getRealPathFromURI(this, getIntent().getParcelableExtra(Intent.EXTRA_STREAM)); public String getRealPathFromURI(Context context, Uri contentUri) { Cursor cursor = null; try { String[] proj = {MediaStore.Images.Media.DATA}; cursor = context.getContentResolver().query(contentUri, proj, null, null, null); if (cursor == null) return contentUri.getPath(); int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); cursor.moveToFirst(); return cursor.getString(column_index); } finally { if (cursor != null) { cursor.close(); }

On my Google Play console I see quite a lot crash reports since I started to use Dagger 2, but only on Android 7.0 and mainly on Samsung devices, some Huawai and Motorola devices and some rare Xperia devices: java.lang.RuntimeException: at android.app.ActivityThread.performLaunchActivity (ActivityThread.java:2984) at android.app.ActivityThread.handleLaunchActivity (ActivityThread.java:3045) at android.app.ActivityThread.-wrap14 (ActivityThread.java) at android.app.ActivityThread$H.handleMessage (ActivityThread.java:1642) at android.os.Handler.dispatchMessage (Handler.java:102) at android.os

I am trying to run the APK on API 22 device after updating compileSdkVersion to N but unable to do so. compileSdkVersion 'android-N' buildToolsVersion "24.0.0 rc1" defaultConfig { minSdkVersion 14 targetSdkVersion 'N' } Out of the box, the build tools are set up to block you from running N Developer Preview apps on older devices. Presumably, this is a sloppy way for Google to try to prevent people from shipping stuff built off of the preview. This approach was also used in the past two developer previews. So, Google does not want you testing your N Developer Preview app on your Android 5.0

My app has been humming along nicely through various Android versions. I have users running it on Android 4.3, 5.0, 5.1 and 6.0 with no problems. However a user with a S7 Edge has just updated with Android 7.0 and the app is crashing when text is pasted into an EditText field (This is the first and only thing you do with this app - it starts you paste in text into a box and then the app parses the text). I have looked at many threads on Null Pointer Exceptions and I have looked at the source for Editor.java but nothing is obvious. The stack trace below shows no problems with my code. Any ideas
