In my app I have a custom auto download and install APK it works like this
// auto register for the complete download
activity.registerReceiver(onComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
// Download the file through DownloadManager
String destination = Environment.getExternalStorageDirectory() + "/";
String fileName = "myfile.apk";
destination += fileName;
final Uri uri = Uri.parse("file://" + destination);
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(apkUrl));
request.setDescription("description");
request.setTitle("title");
request.setDestinationUri(uri);
final DownloadManager manager = (DownloadManager) activity.getSystemService(Context.DOWNLOAD_SERVICE);
final long downloadId = manager.enqueue(request);
onComplete = new BroadcastReceiver() {
public void onReceive(Context ctxt, Intent intent) {
Intent install = new Intent(Intent.ACTION_VIEW);
// BEFORE working doing this
//install.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
//install.setDataAndType(uri,
// manager.getMimeTypeForDownloadedFile(downloadId));
// Using file provider it doesnt work
Uri apkUri = FileProvider.getUriForFile(AutoUpdate.this,
"com.myapp", file);
install.setDataAndType(apkUri,manager.getMimeTypeForDownloadedFile(downloadId));
activity.startActivity(install);
activity.unregisterReceiver(this);
}
};
Android manifest:
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.myapp"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
Provider_path (Sorry for some reason so cuts the path tag)
external-path name="myfolder" path="."/>
When the file finished to download the onComplete is called but the activiy doesn't start:
No Activity found to handle Intent { act=android.intent.action.VIEW dat=content://com.myapp/myfolder/myfile.apk typ=application/vnd.android.package-archive flg=0x4000000 }
When using the normal file:// it does work
Is there something I'm missing when using the file provider? Does the activity doesn't start because the file is not found ? Do I need extra permission ? (at the moment I have INTERNET, READ and WRITE on external storage)
The package installer only supports content
schemes starting on Android 7.0. Prior to that — and despite documentation to the contrary — the package installer only supports file
schemes.
You will need to set the Uri
on your Intent
differently based on whether you are running on Android 7.0+ or not, such as by branching on Build.VERSION.SDK_INT
.
Commonware is right, For those looking for the code:
BroadcastReceiver onComplete = new BroadcastReceiver() {
public void onReceive(Context ctxt, Intent intent) {
downloadButton.setEnabled(true);
downloadButton.setText("Terminado");
progressbar.setVisibility(View.GONE);
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.N){
Intent install = new Intent(Intent.ACTION_VIEW);
install.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
Uri apkURI = FileProvider.getUriForFile(
self,
self.getApplicationContext()
.getPackageName() + ".provider", file);
install.setDataAndType(apkURI,
manager.getMimeTypeForDownloadedFile(downloadId));
install.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(install);
} else{
String destination = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/";
String fileName = "surveyevent.apk";
destination += fileName;
Uri uri = Uri.parse("file://" + destination);
Intent install = new Intent(Intent.ACTION_VIEW);
install.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
install.setDataAndType(uri,
manager.getMimeTypeForDownloadedFile(downloadId));
startActivity(install);
}
unregisterReceiver(this);
finish();
}
};
Your provider is not found because
android:enabled="true"
is missing in your manifest.
But then it will not work either reading the other answer of CW.
