I want to download .apk file and install it. When I'm not using FileProvider, everything is going well, but when I create uri from file using FileProvider, I've got IllegalArgumentException: Not a file URI: content://pl.rasztabiga.klasa1a.provider/external_storage_root/klasa1a.apk on line
final long downloadId = manager.enqueue(request);
I tried everything from stackoverflow but nothing helped. Here is my code:
File file = new File(Environment.getExternalStorageDirectory(), "klasa1a.apk");
final Uri uri = FileProvider.getUriForFile(MainActivity.this, getApplicationContext().getPackageName() + ".provider", file);
//Delete update file if exists
//File file = new File(destination);
if (file.exists())
file.delete();
//get url of app on server
String url = "http://rasztabiga.ct8.pl/klasa1a.apk";
//set downloadmanager
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.setDescription("Downloading new version");
request.setTitle(MainActivity.this.getString(R.string.app_name));
//set destination
request.setDestinationUri(uri);
// get download service and enqueue file
final DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
final long downloadId = manager.enqueue(request);
//set BroadcastReceiver to install app when .apk is downloaded
BroadcastReceiver onComplete = new BroadcastReceiver() {
public void onReceive(Context ctxt, Intent intent) {
Intent install = new Intent(Intent.ACTION_VIEW);
install.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
install.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
install.setDataAndType(uri,
manager.getMimeTypeForDownloadedFile(downloadId));
startActivity(install);
unregisterReceiver(this);
finish();
}
};
//register receiver for when .apk download is compete
registerReceiver(onComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
ACTION_VIEW
and ACTION_INSTALL_PACKAGE
only support the content
scheme as of Android 7.0. Prior to that, you have no choice but to use file
. So, change:
final Uri uri = FileProvider.getUriForFile(MainActivity.this, getApplicationContext().getPackageName() + ".provider", file);
to:
final Uri uri = (Build.VERSION.SDK_INT>=Build.VERSION_CODES.N) ?
FileProvider.getUriForFile(MainActivity.this, BuildConfig.APPLICATION_ID + ".provider", file) :
Uri.fromFile(file);
The problem was in DownloadManager. It cannot parse uri's as "content://", only as "file://" so since sdk24, we cannot use it. Using common IOStreams and HttpURLConnection everything works fine. Thanks to @CommonsWare for showing me his project. That's how it looks like now:
File file = new File(Environment.getExternalStorageDirectory(), "klasa1a.apk");
final Uri uri = (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) ?
FileProvider.getUriForFile(MainActivity.this, BuildConfig.APPLICATION_ID + ".provider", file) :
Uri.fromFile(file);
//Delete update file if exists
//File file = new File(destination);
if (file.exists())
//file.delete() - test this, I think sometimes it doesnt work
file.delete();
//get url of app on server
String url = "http://rasztabiga.ct8.pl/klasa1a.apk";
InputStream input = null;
OutputStream output = null;
HttpURLConnection connection = null;
try {
URL sUrl = new URL(url);
connection = (HttpURLConnection) sUrl.openConnection();
connection.connect();
// download the file
input = connection.getInputStream();
output = new FileOutputStream(file);
byte data[] = new byte[4096];
int count;
while ((count = input.read(data)) != -1) {
// allow canceling with back button
if (isCancelled()) {
input.close();
return null;
}
output.write(data, 0, count);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (output != null)
output.close();
if (input != null)
input.close();
} catch (IOException ignored) {
}
if (connection != null)
connection.disconnect();
}
Intent install = new Intent(Intent.ACTION_INSTALL_PACKAGE)
.setData(uri)
.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(install);
return null;
}
For those that still want to use DownloadManager
and find that the answer by CommonsWare doesn't solve the problem, you need to include an exception for APK file
final Uri uri = (!file.getAbsolutePath().endsWith(".apk") && Build.VERSION.SDK_INT>=Build.VERSION_CODES.N) ?
FileProvider.getUriForFile(MainActivity.this, BuildConfig.APPLICATION_ID + ".provider", file) :
Uri.fromFile(file);
request.setDestinationUri(uri);
Which is a shorter version of
if (!file.getAbsolutePath().endsWith(".apk") && Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
request.setDestinationUri(FileProvider.getUriForFile(MainActivity.this, BuildConfig.APPLICATION_ID + ".provider", download));
} else {
request.setDestinationUri(Uri.fromFile(file));
}
that may be easier to follow.
The short answer is that apk files should be handled with Uri.fromFile
, but this does not have to come at the cost of changing the entire process.
If you want to be thorough, though, you can also catch the IllegalArgumentException
for Not a file URI
and use that to attempt Uri.fromFile
