I've searching for many other answers about this failure, and no one of them solved my problem.
I have two apps, the app1 is implemented with Content Provider, and one database called students. This db is accessed normally inside app1.
But, when I fetch database from the app2, I've facing this error:
Failed to find provider info for
com.example.a436236692.myapplication.StudentsProvider
The code that are fetching students db is the same from both apps:
Uri myURI = Uri.parse("content://com.example.a436236692.myapplication.StudentsProvider/students");
ContentProviderClient myCR = getContentResolver().acquireContentProviderClient(myURI);
try {
Cursor c = myCR.query(myURI, null, null, null, "name");
if (c.moveToFirst()) {
do{
Toast.makeText(this,
c.getString(c.getColumnIndex(Constantes._ID)) +
", " + c.getString(c.getColumnIndex( Constantes.NAME)) +
", " + c.getString(c.getColumnIndex( Constantes.GRADE)),
Toast.LENGTH_SHORT).show();
} while (c.moveToNext());
}
} catch (RemoteException e) {
e.printStackTrace();
}
Debuging app 2, myCR comes with null. Them crashes application.
With my searches of this problem, I found many information that I need to grant access from package of Content Provider. Below are my manifests:

Even with permissions, inside the app1, Read and Write and other things, that I include inside the manifests, they do not affect the result.

I'm working with GeckoView and met problem with installing AddOns. As suggested on Documentation, I've provided XPI compatible with Android, but nothing changes. Copying file to Assets doesn't make a change. Browser doesn't acknowledge WebExtension.
private fun setupGeckoView() {
geckoSession?.permissionDelegate = object : GeckoSession.PermissionDelegate {
override fun onContentPermissionRequest(
session: GeckoSession,
perm: GeckoSession.PermissionDelegate.ContentPermission
): GeckoResult<Int>? {
return super.onContentPermissionRequest(session, perm)
}
}
geckoView = findViewById(R.id.geckoView)
val runtime = GeckoRuntime.create(this)
runtime.settings.consoleOutputEnabled = true
runtime.webExtensionController.promptDelegate = PromptListener(runtime.webExtensionController)
runtime.webExtensionController
.install("https://addons.mozilla.org/android/downloads/file/3719055/youtube_high_definition-85.0.0-an+fx.xpi")

I'm checking logs and the result is confusing. I've got prompt that WebExtension is installed, but when I looking at controller.list() it's empty.
You may be missing a PermissionDelegate:
geckoSession?.permissionDelegate = object : GeckoSession.PermissionDelegate {
override fun onContentPermissionRequest(
session: GeckoSession,
perm: GeckoSession.PermissionDelegate.ContentPermission
): GeckoResult<Int>? {
return super.onContentPermissionRequest(session, perm)
}
}
Permission delegate allows you to handle requests from Gecko for any permission that needs handling.
I'm getting an handshakeexception handshake error in client (os error wrong_version_number tls_record cc 242) error whenever making an http request( I also tried https ) but from only one ( Cyclist app ) of the two Flutter apps that connect to Node.js server. I'm using the same IP address and port on both, the Android tablet on which I'm testing both apps and for my machine. I checked Manifest Android/src/main/AndroidManifest.xml to see if I was using android:usesCleartextTraffic="true"`on the working app ( Shop app ) but I'm not..
What else could I check to see what's causing the error in the Cyclist app??
This is the request:
Map<String, String> headers = {
'Content-Type': 'application/json',
'api_key': Environment.dbApiKey
};
// final Uri uri = Uri.https(Environment.dbUrl, '/api/routes');
final Uri uri = Uri.http(Environment.dbUrl, '/api/routes');
await post(uri, headers: headers, body: jsonEncode(route.toMap()))
.then((resp) {
print(
'RouteMongoRepository.saveRoute response status code is: ${resp
.statusCode}, \n response is : ${jsonDecode(resp.body)}');
UserRoute saved = UserRoute.fromMap(jsonDecode(resp.body)['data']);
print('saved route to Mongo is : ${saved.toMap().toString()}');
}) .catchError((e) => print('RouteMongoRepository.saveRoute error: $e')) ;
This is the Shop app manifest:

I am trying to write in file after android device boots. I have checked everything related to this topic here but none of them worked for me. My phone is Huawei Honor (H30-U10) and it's rooted. Android version 4.2.2. Here is my code:

try {

os.write(data.getBytes());
os.close();

}
}
Remove
android:permission="android.permission.RECEIVE_BOOT_COMPLETED"
from your <receiver> block.
After trying all of mentioned answers and tricks, I finally find why the code is not work in my phone. Some Android phones like "Huawei Honor 3C Android 4.2.2" have a Statup Manager menu in their settings and your app must be checked in the list. :)
I write a program provider a provider for another apps of our company. The provider need a permission to access the data.
We also have a interface need use NFC send json data to another devices.
When we access the provider in CreateNdefMessageCallback.createNdefMessage like
#Override
public NdefMessage createNdefMessage(NfcEvent event) {
Context context = this;
ContentResolver resolver = context.getContentResolver();
Cursor cursor = resolver.query(Uri.parse("content://demo/data-lists"),
null,
null,
null,
null);
// FIXME Strange: Will never goes here ...
mMessage = getMessage(cursor);
NdefMessage msg = new NdefMessage(
new NdefRecord[] {
createMimeRecord(mMimeType, mMessage.getBytes())
});
return msg;
}
There is very strange, we never get a cursor until remove the permission.
Permission Declear
<permission
android:name="com.client.permission.MY_PERMISSION"
android:label="#string/provider_label"
android:protectionLevel="signatureOrSystem" />
Request permision
<uses-permission android:name="com.client.permission.MY_PERMISSION" />
Provider permission declear
<provider
android:name=".provider.DemoProvider"
android:authorities="demo"
android:multiprocess="true"
android:permission="com.client.permission.MY_PERMISSION" />
Currenty the provider and the NFC-send activity in the same application and read the provider data will but the NFC callback.
And if I remove the permission for the provider, this will work fine.
like the
Provider without permission
<provider
android:name=".provider.DemoProvider"
android:authorities="demo"
android:multiprocess="true"/>
Please help.
Thanks.
UPDATED 2013-03-14
It's very strange. I found this issue only when the provider and the NFC Activity in the same application. like this.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.nfcdemo"
android:versionCode="6"
android:versionName="build-svn291" >
<uses-sdk

android:targetSdkVersion="17" />
<permission
android:name="com.client.permission.MY_PERMISSION"
android:label="#string/provider_label"
android:protectionLevel="signatureOrSystem" />
<uses-permission android:name="com.client.permission.MY_PERMISSION" />
<activity
android:name=".ui.MainTabActivity"
android:label="#string/app_name"
android:screenOrientation="portrait" >

</activity>
<provider
android:name=".provider.DemoProvider"

But if I use two separated application, it works will like.
