I have written a method that check new version of my APP and when it exists, the application download and it should install that. But it can not install the downloaded application and it gives me this error:
There was a problem parsing the package.
But when I uninstall my app and install it again with the downloaded apk file. Everything works fine so my app downloads the file correctly.
But why this could not install it programmatically?
This is my Download code:
public long downloadFromUrl(String url, String fileName, String format) {
String fullFileName = fileName + format;
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url))
.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE)// Visibility of the download Notification
.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, fullFileName)// Uri of the destination file
.setTitle(fullFileName)// Title of the Download Notification
.setDescription("Downloading...");// Description of the Download Notification
DownloadManager downloadManager = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
long id = downloadManager.enqueue(request);
if (format.equals(APK_FORMAT)) {
File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS), fullFileName);
if(file.exists()){
DownloadReceiver downloadReceiver = new DownloadReceiver(file);
Intent intent = new Intent();
downloadReceiver.onReceive(context,intent);
context.registerReceiver(downloadReceiver,new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
}
}
return id;
}
This is a receiver that when download is completed, runs:
#Override
public void onReceive(Context context, Intent intent) {
long receivedId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1);
if (file != null) {
Uri uri = FileProvider.getUriForFile(context,context.getApplicationContext().getPackageName()+ ".provider",file);
intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, "application/vnd.android.package-archive");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
}
Uri uri;
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
uri = FileProvider.getUriForFile(activity, BuildConfig.APPLICATION_ID + ".provider", destination);
} else {
uri = Uri.fromFile(destination);
}
//Log.d("path",uri.getPath());
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
activity.startActivity(intent);
make sure you have added this permission to your manifest file
Also make sure both version of your APKs are signed and with same key.
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
I made it work with this code (destination is file object).

I am trying to add option to update app by downloading apk, its getting installed successfully. But the problem is, app got close after installation, without prompting Open/Done screen in Nougat and above devices.
I have tried using both ACTION_VIEW and ACTION_INSTALL_PACKAGE, but no luck. Also tried with startActivityForResult instead of startActivity, still no luck.
public void installAPK() {
Intent intent = new Intent(Intent.ACTION_INSTALL_PACKAGE);
File file = new File(path + "update.apk");
if (Build.VERSION.SDK_INT < 24) {
intent.setDataAndType(Uri.fromFile(new File(path + "update.apk")), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // without this flag android returned a intent error!
} else {
Uri apkURI = FileProvider.getUriForFile(
activity,
activity.getApplicationContext()
.getPackageName() + ".provider", file);
intent.setDataAndType(apkURI, "application/vnd.android.package-archive");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
intent.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true);
activity.startActivityForResult(intent, RC_INSTALL_APK);
}
Anything I missed to do?
Here's sample code of my application method to open new version
void OpenNewVersion(String location) {
Intent downloadIntent;
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
String PATH = Environment.getExternalStorageDirectory() + "/Download/";
File fileLocation = new File(PATH, "app-stock.apk");
Uri apkUri = FileProvider.getUriForFile(this, "Adapters.GenericFileProvider", fileLocation);
downloadIntent = new Intent(Intent.ACTION_VIEW);
downloadIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
downloadIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
downloadIntent.setDataAndType(apkUri, "application/vnd.android.package-archive");
List<ResolveInfo> resInfoList = this.getPackageManager().queryIntentActivities(downloadIntent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo resolveInfo : resInfoList) {
String packageName = resolveInfo.activityInfo.packageName;
this.grantUriPermission(packageName, apkUri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
} else {
File fileLocation = new File(this.getFilesDir(), "app-stock.apk");
downloadIntent = new Intent(Intent.ACTION_VIEW);
downloadIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
downloadIntent.setDataAndType(Uri.fromFile(fileLocation), "application/vnd.android.package-archive");
}
this.startActivity(downloadIntent);
}
I am generated a folder name "tesApplication" and create a file name "testFile.csc" in it and store some date into that file. Now I want to open folder dir using new intent.
I had try below code but did not work in my case any other way to achieve this.
Uri selectedUri = Uri.parse(fileNameString);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(selectedUri, "text/csv");
if (intent.resolveActivityInfo(getPackageManager(), 0) != null)
{
startActivity(intent);
}
else
{
// if you reach this place, it means there is no any file
// explorer app installed on your device
}
copy this in else
public void openFolder()
{
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()
+ "/myFolder/");
intent.setDataAndType(uri, "text/csv");
startActivity(Intent.createChooser(intent, "Open folder"));
}
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.
I'm trying to open a file using another app, i.e. opening a .jpg with Gallery, .pdf with Acrobat, etc.
The problem I'm having with this is when I try to open the file in the app, it only opens the chosen app instead of opening the file within the app. I tried following Android open pdf file via Intent but I must be missing something.
public String get_mime_type(String url) {
String ext = MimeTypeMap.getFileExtensionFromUrl(url);
String mime = null;
if (ext != null) {
mime = MimeTypeMap.getSingleton().getMimeTypeFromExtension(ext);
}
return mime;
}
public void open_file(String filename) {
File file = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_DOWNLOADS), filename);
// Get URI and MIME type of file
Uri uri = Uri.fromFile(file).normalizeScheme();
String mime = get_mime_type(uri.toString());
// Open file with user selected app
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(uri);
intent.setType(mime);
context.startActivity(Intent.createChooser(intent, "Open file with"));
}
As far as I can tell, it returns the right URI and MIME type:
URI: file:///storage/emulated/0/Download/Katamari-ringtone-985279.mp3
MIME: audio/mpeg
Posting my changes here in case it can help someone else. I ended up changing the download location to an internal folder and adding a content provider.
public void open_file(String filename) {
File path = new File(getFilesDir(), "dl");
File file = new File(path, filename);
// Get URI and MIME type of file
Uri uri = FileProvider.getUriForFile(this, App.PACKAGE_NAME + ".fileprovider", file);
String mime = getContentResolver().getType(uri);
// Open file with user selected app
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(uri, mime);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
}
I used this piece of code and it worked perfectly fine on android 6 and below not tested on the higher version
public void openFile(final String fileName){
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri uri = Uri.fromFile(new File(android.os.Environment.getExternalStorageDirectory()
.getAbsolutePath()+ File.separator+"/Folder/"+fileName));
intent.setDataAndType(uri, "audio/mpeg");
startActivity(intent);
}
[This question may be duplicate, but i din't find what i am looking for]
[Read]How can we open files like ppt, doc, pps, rtf, etc. in Android?
I am having PPT files. In my app, i have a list view which display the PPT file list available in my private app folder. In click of particular file, i want to open corresponding PPT file for reading in my App.
The App which i am creating is just like collection of PPTs and reading them one by one.
Please provide any API/Example/Links.
You need to use other application to open your ppt files , Make sure that file location you are providing is accessible to other application. Try with following :
final Uri uri = Uri.fromFile(file);
final Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, "application/vnd.ms-powerpoint");
PackageManager pm = getPackageManager();
List<ResolveInfo> list = pm.queryIntentActivities(intent, 0);
if(list.size() > 0)
startActivity(context, intent);
Available application will be shown to user and user can choose application which can open.
private void openPPT(final String path) {
File file = new File(path);
Uri uri ;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
uri = FileProvider.getUriForFile(context, context.getPackageName() + ".provider", file);
} else {
uri = Uri.fromFile(file);
}
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.setDataAndType(path, "application/vnd.ms-powerpoint");
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
try {
startActivity(intent);
} catch (ActivityNotFoundException e) {
Toast.makeText(this, "Application not found", Toast.LENGTH_SHORT).show();
}
}
