With Android Studio, Java language, I write an application that install a package which APK is /eduphone/eduphone.apk On Android 12 I get the following error on Logcat : Permission to access file: /storage/emulated/0/Download/eduphone/eduphone.apk is denied
I tried several solutions proposed in Stak Overflow, but none works.
Here is the manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools">
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />
<uses-permission android:name="android.permission.READ_MEDIA_VIDEO" />
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_MEDIA_AUDIO" />
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/>
<uses-permission android:name="com.termux.permission.RUN_COMMAND"/>

</provider>
</application>
<queries>
<package android:name="com.termux" />
<package android:name="eu.edduphone" />
</queries>
</manifest>`
Here is provider_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path
name="external_files"
path="." />
</paths>
Here is the Java code for permission :
public void getdroits () {
if (ContextCompat.checkSelfPermission(this, READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{READ_EXTERNAL_STORAGE}, 1);
}
if (ContextCompat.checkSelfPermission(this, WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{WRITE_EXTERNAL_STORAGE}, 1);
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
if(!getPackageManager().canRequestPackageInstalls()){
startActivityForResult(new Intent(Settings.ACTION_MANAGE_UNKNOWN_APP_SOURCES)
.setData(Uri.parse(String.format("package:%s", getPackageName()))), 1);
}
}
}
Here is Java code for the APK insttallation. The argument passed to this code is String PATH = "/sdcard/Download/eduphone/eduphone.apk"
private void instApp(String PATH){
Context context = getActivity().getBaseContext();
File file = new File(PATH);
if(file.exists()) {
Uri uri ;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
uri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", file);
} else {
uri = Uri.fromFile(file);
}
Intent intent = new Intent(Intent.ACTION_INSTALL_PACKAGE, uri);
intent.setDataAndType(uri, "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
try {
context.startActivity(intent);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
Log.e("TAG", "Error in opening the file!");
}
}else{
Toast.makeText(context,"APK "+PATH+" not found",Toast.LENGTH_LONG).show();
}
}
Thank you for your help ! Thierry
The answer of @Commonsware is rigth. But in my case I do not plan to publish this app on a store. This app is an installer for very few people which will want to install a specific environment on their smartphone (a Moodle server + a Nextcloud running thanks to Termux App). They will have to validate my global conditions before anything else.
That why I solve my problem by allowing MANAGE_EXTERNAL_STORAGE
For that :
I add in the manifest.xml :
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_MEDIA_AUDIO" />
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/>
At the early beginning of my app, I check and request permissions as seen in How to obtain MANAGE_EXTERNAL_STORAGE permission and How to check if Manifest.permission.MANAGE_EXTERNAL_STORAGE is granted? :
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
if (!Environment.isExternalStorageManager()) {
//request for the permission
Log.d("Thierry", "Request ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION");
Intent intent = new Intent(Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION);
Uri uri = Uri.fromParts("package", getPackageName(), null);
intent.setData(uri);
startActivity(intent);
}
}
Then for app installation :
private void instApp(String PATH){
Context context = getActivity().getBaseContext();
Log.d("Thierry", "Install PATH : "+PATH);
File file = new File(PATH);
if(file.exists()) {
Uri uri ;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
Log.d("Thierry", "Build.VERSION.SDK_INT >= Build.VERSION_CODES");
uri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", file);
} else {
uri = Uri.fromFile(file);
Log.d("Thierry", "Build.VERSION.SDK_INT < Build.VERSION_CODES");
}
Log.d("Thierry", "INSTAPK URI="+uri.toString());
Intent intent = new Intent(Intent.ACTION_INSTALL_PACKAGE, uri);
intent.setData(uri);
intent.setDataAndType(uri, "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION| Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION);
try {
context.startActivity(intent);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
Log.d("TAG", "Error in opening the file!");
}
}else{
Log.d("Thierry", "INSTAPP , Not existe"+PATH);
}
}
