Android 7 open APK with ACTION_VIEW not working (Package installer has stopped)

Question

My app has an auto update feature which download an APK and then uses a Intent.ACTION_VIEW to open the package installer.

Up to 7 it worked perfectly (by feeding the Intent with a normal file://)

With Android 7 I had to change to use a FileProvider. The only difference in the code is:

Intent installIntent = new Intent(Intent.ACTION_VIEW);
          if (android.os.Build.VERSION.SDK_INT <= Build.VERSION_CODES.M) {
            installIntent.setDataAndType(uri,
                manager.getMimeTypeForDownloadedFile(downloadId));
          } else {

            Uri apkUri = FileProvider.getUriForFile(AutoUpdate.this,
                BuildConfig.APPLICATION_ID, file);
              installIntent.setDataAndType(apkUri,manager.getMimeTypeForDownloadedFile(downloadId));
          }
          activity.startActivity(installIntent);

Once the startActivity is called I get this every single time

Is this a bug with Android 7 ? Or something/permission is missing my side ?

The path xmlfile

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">

</paths>

Answer 1

try like below, it helped me and its working in Android N7.0.

File toInstall = new File(appDirectory, appName + ".apk");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
    Uri apkUri = FileProvider.getUriForFile(activity, BuildConfig.APPLICATION_ID + ".provider", toInstall);
    Intent intent = new Intent(Intent.ACTION_INSTALL_PACKAGE);
    intent.setData(apkUri);
    intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    activity.startActivity(intent);
} else {
    Uri apkUri = Uri.fromFile(toInstall);
    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(apkUri, "application/vnd.android.package-archive");
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    activity.startActivity(intent);
}

Try to add read uri permission to your intent:

installIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
