I am trying to attach a pdf file from Downloads folder of internal storage to Gmail app using Intent. But it gives me error of Unable to attach the file. I am using FileProvider for getting the file of downloads folder. Here is the code that I have written.
MainActivity
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
File pdfDirectory = new File(Environment.getExternalStorageDirectory(), "Download");
File pdfFile = new File(pdfDirectory, "fileName.pdf");
Uri pdfFileContentUri = FileProvider.getUriForFile(this, APPLICATION_ID + ".fileprovider", pdfFile);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("application/pdf");
intent.putExtra(Intent.EXTRA_STREAM, pdfFileContentUri);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
}

I want to have the abilities to update my app from my application, so I can download my apk file ( each of them are signed ). And when the installation want to start:
First of all: I have preparation of installation popup which appear
Then: another popup appear and told me "A problem occurred while parsing the package"
My error is like this:
So my app, didn't update. Could you help me please ?
I use Xamarin Forms but especially for Android.
Manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" package="com.MyCompany.clamexdroid" android:installLocation="preferExternal">

My function when I click on my update Button
private async Task update()
{
this.popupIsVisible = false;
this.IsBusy = true;
string uri = "myLink.apk";
HttpClient cli = new HttpClient();
await cli.DownloadBasicFile(uri, DependencyService.Get<IDeviceDependency>().GetExternalAPKPath());
DependencyService.Get<IDeviceDependency>().InstallApk();
this.IsBusy = false;
}
And my InstallApk() function ( I'm sure that the file is downloaded )
public void InstallApk()
{
Intent promptInstall = new Intent(Intent.ActionView).SetDataAndType(
Android.Net.Uri.Parse($"content:///{this.GetExternalAPKPath()}"),"application/vnd.android.package-archive");
promptInstall.SetFlags(ActivityFlags.NewTask);
promptInstall.AddFlags(ActivityFlags.GrantReadUriPermission);
Android.App.Application.Context.StartActivity(promptInstall);
}
public string GetExternalAPKPath()

try
{
return Path.Combine(Android.App.Application.Context.GetExternalFilesDir("").AbsolutePath, "com.MyCompany.clamexdroid.apk");
}
catch (Exception e) { Console.WriteLine(e.Message); }
return "";
}
At first, you can check the apk file you had downloaded has any damage. And then you can try to the following steps to install the apk:
1.Add the provider in the AndroidManifest.xml, such as:
<application android:allowBackup="true" android:icon="#drawable/androidicon" android:label="#string/app_name" android:supportsRtl="true" android:theme="#style/AppTheme">
<provider android:name="androidx.core.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>
</application>
2.Create the provider_paths.xml in the folder named xml below the values folder in the android part.
<paths >
<external-path
name="external_files"
path="." />
</paths>
3.Use the following code to install the apk:
var path = Path.Combine(Android.App.Application.Context.GetExternalFilesDir("").AbsolutePath, "com.MyCompany.clamexdroid.apk");
Java.IO.File file = new Java.IO.File(path);
Intent install = new Intent(Intent.ActionView);
Android.Net.Uri apkURI = FileProvider.GetUriForFile(this, this.ApplicationContext.PackageName + ".provider", file);
install.SetDataAndType(apkURI, "application/vnd.android.package-archive");
install.AddFlags(ActivityFlags.NewTask);
install.AddFlags(ActivityFlags.GrantReadUriPermission);
StartActivity(install);
Please don't mark it duplicate before reading it
I have searched through all the links on stackoverflow and Github for a possible answer but still am getting the same error.
Here is the Manifest file:
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">

</activity>
<provider android:authorities="com.example.aditya.pdf_report"

android:readPermission="com.company.aditya.pdf_report.READ">
<meta-data android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths"/>
</provider>
</application>
Here is Java file:
File filelocation = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/pdf_report/" + reportname.getText().toString().trim() + ".pdf" );
Uri path;
path = FileProvider.getUriForFile(MainActivity.this, getPackageName(),filelocation);
Intent emailIntent = new Intent(Intent.ACTION_SEND);
// set the type to 'email'
emailIntent .setType("vnd.android.cursor.dir/email");
emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
emailIntent .putExtra(Intent.EXTRA_STREAM, path);
// the mail subject
emailIntent .putExtra(Intent.EXTRA_SUBJECT, "Here is the Branch Visit Report - Human Resources");
startActivity(Intent.createChooser(emailIntent , "Send email..."));
here is file-paths.xml:
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<files-path name="pdf_report" path="pdf_report/"/>
</paths>
here is my package name:
com.example.aditya.pdf_report
Here is where the Pdf is saved on my phone:
Environment.getExternalStorageDirectory().getAbsolutePath() + "/pdf_report"
I have followed all the links but I think its the file-paths.xml where I am writing wrong stuff
change your file-path.xml as below. It may be work.
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path
name="external_files"
path="." />
</paths>
I want to install an apk in my application and I'm using this method but all the time I get the errors listed below:
Code
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/test.apk");
Uri fileUri = Uri.fromFile(file);
if (Build.VERSION.SDK_INT >= 24) {
fileUri = FileProvider.getUriForFile(DLActivity.this, "codenevisha.com.apps.bartarinapp.provider",file);
}
Intent intent = new Intent(Intent.ACTION_VIEW, fileUri);
intent.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true);
intent.setDataAndType(fileUri, "application/vnd.android" + ".package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
And this is my manifest:

Why is this error happening?
Your FileProvider is misconfigured. Your FileProvider metadata needs an <external-path> element, and you do not have one. See the documentation.
I tested the below code.
Add below permission in Menifest
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Below code for installing package
//// TODO: 1/16/18 Check the external storage permission
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/test.apk");
Uri fileUri = Uri.fromFile(file);
if (Build.VERSION.SDK_INT >= 24) {
String packageId = getApplicationContext().getPackageName();
fileUri = FileProvider.getUriForFile(MainActivity.this, packageId + ".files", file);
}
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true);
intent.setDataAndType(fileUri, "application/vnd.android" + ".package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
Provider in Menifest
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.files"
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>
<external-path name="external" path="/"/>
Per the Android documentation on EXTRA_NOT_UNKNOWN_SOURCE:
For this to work you must start the installer with startActivityForResult().
I'm getting this exception when trying to use FileProvider:
Java.Lang.IllegalArgumentException: Unable to find configured root for content://com.abc/Android/data/com.abc/files/345345345.pdf Java.Lang.IllegalArgumentException
I guess my file_paths.xml configures the FileProvider with the wrong path. My code:
file_paths.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path path="." name="." />
<files-path path="com.abc/Android/data/com.abc/files/" name="files" />
</paths>
androidManifest.xml
<application android:label="#string/AppName" android:icon="#drawable/ic_launcher">
<meta-data android:name="com.google.android.gms.version" android:value="#integer/google_play_services_version" />
<provider android:name="android.support.v4.content.FileProvider" android:authorities="com.abc" android:exported="false" android:grantUriPermissions="true">
<meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="#xml/file_paths" />
</provider>
</application>
What values should I put in path and name in file_paths.xml, to expose the file with the content URI: content://com.abc/Android/data/com.abc/files/345345345.pdf?
my code which creates the URI:
File newFile = new File (Application.Context.FilesDir.AbsolutePath, filename);
Android.Net.Uri androidContentUri = FileProvider.GetUriForFile (Application.Context, Application.Context.PackageName, newFile);
System.Uri systemContentUri = SystemUri (androidContentUri);
return systemContentUri;
Your entry:
<files-path path="com.abc/Android/data/com.abc/files/" name="files" />
Should become:
<files-path path="files" name="files" />
Path in this case represents the files in the files/ subdirectory of your app's internal storage area.
This application private subdirectory is the same as the value returned:
Application.Context.FilesDir;
So the file location within your app is:
var path = Path.Combine(Application.Context.FilesDir.AbsolutePath, "files");

i want to take a Photo after clicking on a button. But i am getting NullPointerException when trying to get URI with FileProvider.
Here is my ErrorCode:

The Problem-Line seems to be:
mUri = FileProvider.getUriForFile(getApplication().getApplicationContext(),
"ibas.provider", file);
Here´s my Code:
public void takePicture(View view) throws IOException {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
try{
File file = createImageFile();
mUri = FileProvider.getUriForFile(getApplication().getApplicationContext(),
"ibas.provider", file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mUri);
startActivityForResult(intent, REQUEST_IMAGE_CAPTURE);
} catch (IOException e){
e.printStackTrace();
}
}
private File createImageFile() throws IOException {
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
return image;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
String path = "sdcard/orosol/captured_image.jpg";
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == Activity.RESULT_OK) {
Log.i("uri-data", "Uri: " + mUri.toString());
mBitmap = getBitmapFromUri(mImageView,BildActivity.this,mUri);
mImageView.setImageBitmap(mBitmap);
mImageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
}
}

The provider tag is outside of the application tag in the manifest file .
You should add it inside the <application></application> tag
