How to download and install an apk file in Android programming. We have problems with Android 6 and above.
dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(file_url));
enqueue = dm.enqueue(request);
receiver3 = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
long downloadId = intent.getLongExtra(
DownloadManager.EXTRA_DOWNLOAD_ID, 0);
DownloadManager.Query query = new DownloadManager.Query();
query.setFilterById(enqueue);
Cursor c = dm.query(query);
if (c.moveToFirst()) {
int columnIndex = c
.getColumnIndex(DownloadManager.COLUMN_STATUS);
if (DownloadManager.STATUS_SUCCESSFUL == c
.getInt(columnIndex)) {
String uriString = c.getString(c.getColumnIndex(DownloadManager.COLUMN_TITLE));
String uriString2 = c.getString(c.getColumnIndex(DownloadManager.COLUMN_URI));
Intent intent2 = new Intent(Intent.ACTION_VIEW);
intent2.setDataAndType(Uri.fromFile(new File(uriString2)), "application/vnd.android.package-archive");
intent2.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent2);
}
}
}
}
};
StartActivity.this.registerReceiver(receiver3, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
