using fileProvider from service context - android

I want to show a notification and when user clicked install an APK file.
I know how to use the fileProvider itself but I have problem with service context.
Here is my code
manifest:
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.company.app"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/filepaths" />
</provider>
filePaths:
<paths>
<external-path
name="externalFiles"
path="." />
</paths>
service Code:
resultIntent = new Intent(Intent.ACTION_VIEW);
Uri uri;
File file = FileHelper.getApkFile(item.getLink());
if (Build.VERSION.SDK_INT >= 24) {
uri = FileProvider.getUriForFile(
NotificationService.this,
NotificationService.this.getApplicationContext().getPackageName(),
file);
NotificationService.this.setResult(Activity.RESULT_OK,
resultIntent);
} else {
uri = Uri.fromFile(file);
}
resultIntent.setDataAndType(uri, "application/vnd.android.package-archive");
resultIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
as you know setResult() is not available in service.
How can I grant permission from service context?
thank you every one.

I found the problem
I had to add this permission to my manifest to install apk file.
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />

How to install an apk once downloaded in app, or pop up requesting install?

I have created a html page with tables that lists android apks.
I also have an APK which displays the html page, when clicking the download button it downloads the chosen APK... Perfect!
What I want to do is once the download is complete it requests to install the application.
I've tried a few things but it's too much for me to do, would anyone mind helping for some beer tokens,
Thanks
You can add a BroadcastReceiver as a callback when your download completes , and then call the following method inside that callback-
public static void installapk(File apkFile, Context context) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
if (apkFile.exists()) {
Intent install = new Intent(Intent.ACTION_VIEW);
install.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
install.setDataAndType(Uri.fromFile(apkFile),
"application/vnd.android.package-archive");
Uri apkUri =
FileProvider.getUriForFile(context, "com.yourcompany.yourapp.fileprovider", apkFile);
install.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
install.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
install.setDataAndType(apkUri, "application/vnd.android.package-archive");
context.startActivity(install);
} else {
install.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
install.setDataAndType(Uri.fromFile(apkFile),
"application/vnd.android.package-archive");
context.startActivity(install);
}
} else {
System.out.println("apk doesnot exist.");
}
}
}
Don't forget to add this permission in your AndroidManifest.xml file -
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
You also need to create a fileprovider authority in your AndroidManifest.xml -
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.fileProvider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths"/>
</provider>
Then Create a new xml File inside res/xml folder named file_paths.xml and paste this code -
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path
name="external"
path="." />
<external-files-path
name="external_files"
path="." />
<files-path
name="files"
path="." />
</paths>
Happy Coding!

FileProvider: Installing APK. There was an error parsing the package

I am trying to install apk after it has been downloaded by the download manager. I am using a broadcast to get the message after download completes. This is my code below:-
FileProvider: Installing APK. There was an error parsing the package.
val file = File(getExternalFilesDir("Download"), "/playlist/update.apk")
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
val apkUri = FileProvider.getUriForFile(this#MainActivity, BuildConfig.APPLICATION_ID + ".provider", file)
val intent = Intent(Intent.ACTION_INSTALL_PACKAGE)
intent.data = apkUri
intent.flags= Intent.FLAG_GRANT_READ_URI_PERMISSION
this#MainActivity.startActivity(intent)
} else {
val apkUri = Uri.fromFile(file)
val intent = Intent(Intent.ACTION_VIEW)
intent.setDataAndType(apkUri, "application/vnd.android.package-archive")
intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK
this#MainActivity.startActivity(intent)
}
Manifest:-
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/filepaths" />
</provider>
filespath.xml :-
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-files-path name="Download" path="Download/" />
</paths>
I am downloading the apk in "Downloads/playlist/" dir. I saw this same problem - here. However I have can't seem to get it working from that solution. I also checked the apk by installing it myself and it gets installed without any errors. Please help.

My app crashed when open camera in Android 7.0

My app crashed when open camera in Android 7.0
File captureFilePath = new File(cachePath, CommonUtil.getDateTimeForFileName(System.currentTimeMillis())+".jpg");
Uri uri = Uri.fromFile(captureFilePath);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, uri);
startActivityForResult(intent, REQUEST_CAPTURE_IMAGE);
CAPTURE_IMAGE_PATH = captureFilePath.getAbsolutePath();
If your targetSdkVersion >= 24, then we have to use FileProvider class to give access to the particular file or folder to make them accessible for other apps.
1) First Add a FileProvider tag in AndroidManifest.xml under tag as below:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
...
<application
...
<provider
android:name=".GenericFileProvider"
android:authorities="${applicationId}.my.package.name.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
</application>
</manifest>
2) Then create a provider_paths.xml file in res/xml folder. Folder may be needed to created if it doesn't exist.
<paths>
<external-path name="external_files" path="."/>
</paths>
3) Now edit your activity class file as below:
Uri uri = Uri.fromFile(captureFilePath);
to
Uri uri = FileProvider.getUriForFile(this, BuildConfig.APPLICATION_ID, captureFilePath);

Xamarin Android 7+ install APK programmatically

I am trying to install an .apk I have downloaded to the downloads folder in Android 7.
I have tried the way recommended in a number of StackOverflow posts and here https://inthecheesefactory.com/blog/how-to-share-access-to-file-with-fileprovider-on-android-nougat/en by using a FileProvider:
File file = new File(fileUri);
//using Android.Support.V4.Content;
var downloadUri = FileProvider.GetUriForFile(context,context.ApplicationContext.PackageName + ".com.package.name.provider", file);
Intent install = new Intent(Intent.ActionInstallPackage);
install.AddFlags(ActivityFlags.GrantReadUriPermission);
install.AddFlags(ActivityFlags.GrantWriteUriPermission);
install.AddFlags(ActivityFlags.GrantPersistableUriPermission);
install.SetDataAndType(downloadUri, "application/vnd.android.package-archive");
context.StartActivity(install);
AndroidManifest.xml
<uses-permission android:name="android.permission.INSTALL_PACKAGES" />
<application android:label="Settings" android:icon="#drawable/Icon" android:theme="#style/myTheme">
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.com.package.name.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
</application>
provider_paths.xml
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="." />
</paths>
The "downloadUri" looks like: "content://com.package.name.com.package.name.provider/external_files/Download/Sensors%2520Multitool_1.3.0_apk-dl.com.apk"
The error when the installation window pops up is: "There was a problem parsing the package".
I have installed this package by clicking on it in the downloads folder and it installs fine, I have also tried other .apk's with the same issue.
File file = new File(fileUri);
if(Build.VERSION.SdkInt >= Build.VERSION_CODES.N) {
Uri apkUri = FileProvider.GetUriForFile(context, context.ApplicationContext.PackageName + ".provider", toInstall);
Intent intentS = new Intent(Intent.ActionInstallPackage);
intentS.SetData(apkUri);
intentS.SetFlags(ActivityFlags.GrantReadUriPermission);
context.StartActivity(intentS);
} else {
Uri apkUri = Uri.FromFile(toInstall);
Intent intentS = new Intent(Intent.ActionView);
intentS.SetDataAndType(apkUri, "application/vnd.android.package-archive");
intentS.SetFlags(ActivityFlags.NewTask);
context.StartActivity(intentS);
}
It appears that the issue in parsing the package was due to the space in the package name "Sensors%2520Multitool_1.3.0_apk-dl.com.apk".
As soon as the space was removed the package installed correctly.

Android taking picture with FileProvider

I'm taking a picture on Android Nougat with FileProvider, that's my code
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.mypackage.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths" />
</provider>
file_paths.xml:
<paths>
<files-path name="img" path="images/" />
</paths>
Java:
String fileName = "cameraOutput" + System.currentTimeMillis() + ".jpg";
File imagePath = new File(getContext().getFilesDir(), "images");
File file = new File(imagePath, fileName);
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
final Uri outputUri = FileProvider.getUriForFile(activity, "com.mypackage.fileprovider", file);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputUri);
getContext().grantUriPermission(
"com.google.android.GoogleCamera",
outputUri,
Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION
);
cameraIntent.setFlags(FLAG_GRANT_WRITE_URI_PERMISSION);
activity.startActivityForResult(cameraIntent, ACTIVITY_REQUEST_CODE);
Camera activity starts, take picture successfully, but the Activity Result is not OK and the only thing I see in error logs is
CAM_StateSavePic: exception while saving result to URI: Optional.of(content://com.mypackage.fileprovider/img/cameraOutput1469383289530.jpg)
FileNotFoundException: Is a directory
EDIT
missed File#createNewFile();
The main thing to get camera and gallery URI working is provider paths.
you need to create a provider_paths.xml to /res/xml/ dir
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
In your manifest file add this lines between
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths">
</provider>
One more thing, I've found that we need to set vmPolicy in Application class like this
#Override
public void onCreate() {
super.onCreate();
//Allowing Strict mode policy for Nougat support
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
}
Double check your camera and external storage permission in manifest file and there you go with nougat URI.
For more details check this link : Android N FileUriExposedException
if androidx was used in your project, you need replace dot(.) to slash(/).
<!--别用. 不然在androidx上面有问题-->
<external-path name="sdcard" path="/" />
works for me great!
