How to Capture or Upload Image from Gallery using File Provider

We often Pick images from Gallery to upload in android app but sometime when tried in Android version greater than Marshmallow it throw an error that it does not have permission to Uri. So here i am telling you how to use concept of File provider in Android Version after Android Marshmallow .So lets Start from beginning :-


Step 1:

in AndroidManifest.xml add these Permissions

<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />


Step 2:

in Same AndroidManifest.xml file add

 <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_path" />
        </provider>


Step 3:

Create an xml Folder Under res and create a file  provider_path.xml and paste this code inside

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path
        name="external_files"
        path="." />
</paths>

Step 4:

in  Java file add these code to upload image from gallery or capture from camera

 Button btproof;  
 btproof.setOnClickListener(new View.OnClickListener() {  
   @Override  
   public void onClick(View v) {  
     selectImage();  
   }  
 });  
 private void selectImage() {  
   if (ContextCompat.checkSelfPermission(ctx, android.Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {  
     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {  
       givePermission(); // Take Real time permission from user to access camera and media files  
     }  
   } else {  
     final CharSequence[] options = {  
       "Take From Camera",  
       "Choose from Gallery",  
       "Cancel"  
     };  
     AlertDialog.Builder builder = new AlertDialog.Builder(this);  
     builder.setTitle("Pick a Proof !");  
     builder.setItems(options, new DialogInterface.OnClickListener() {  
       @Override  
       public void onClick(DialogInterface dialog, int item) {  
         if (options[item].equals("Take From Camera"))  
         {  
           Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);  
           File f = new File(Environment.getExternalStorageDirectory(), "temp.jpg");  
           if (Build.VERSION.SDK_INT > Build.VERSION_CODES.M) {  
             intent.putExtra(MediaStore.EXTRA_OUTPUT, FileProvider.getUriForFile(ctx, ctx.getApplicationContext().getPackageName() + ".provider", f));  
             intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);  
             intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);  
             startActivityForResult(intent, 1);  
           } else {  
             intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);  
             f = new File(Environment.getExternalStorageDirectory(), "temp.jpg");  
             intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));  
             startActivityForResult(intent, 1);  
           }  
         } else if (options[item].equals("Choose from Gallery"))  
         {  
           Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);  
           startActivityForResult(intent, 2);  
         } else if (options[item].equals("Cancel")) {  
           btproof.setText("Select Photo ");  
           dialog.dismiss();  
         }  
       }  
     });  
     builder.show();  
   }  
 }  
 public String getStringImage(Bitmap bmp) {  
   ByteArrayOutputStream baos = new ByteArrayOutputStream();  
   bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);  
   byte[] imageBytes = baos.toByteArray();  
   String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);  
   return encodedImage;  
 }  
 public void givePermission() {  
   //tedpermission library for real time android permissions  
   PermissionListener permissionlistener = new PermissionListener() {  
     @Override  
     public void onPermissionGranted() {  
     }  
     @Override  
     public void onPermissionDenied(ArrayList deniedPermissions) {  
       Toast.makeText(this, "Permission Denied\n" + deniedPermissions.toString(), Toast.LENGTH_SHORT).show();  
     }  
   };  
   new TedPermission(this)  
     .setPermissionListener(permissionlistener)  
     .setDeniedMessage("If you reject permission,you can not use this service\n\nPlease turn on permissions at [Setting] > [Permission]")  
     .setPermissions(Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.CAMERA)  
     .check();  
 }  
 @Override  
 public void onActivityResult(int requestCode, int resultCode, Intent data) {  
     super.onActivityResult(requestCode, resultCode, data);  
     if (data != null) {  
       if (requestCode == 1) {  
         File f = new File(Environment.getExternalStorageDirectory().toString());  
         for (File temp: f.listFiles()) {  
           if (temp.getName().equals("temp.jpg")) {  
             f = temp;  
             break;  
           }  
         }  
         try {  
           Bitmap bitmap;  
           BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();  
           bitmap = BitmapFactory.decodeFile(f.getAbsolutePath(), bitmapOptions);  
           ivproof.setImageBitmap(bitmap);  
           imageString = getStringImage(bitmap);  
           Toast.makeText(ctx, "Image=" + imageString, Toast.LENGTH_SHORT).show();  
           btproof.setText("Uploaded");  
         } catch (Exception e) {  
           e.printStackTrace();  
         }  
       }  
       if (requestCode == 2) {  
         Uri selectedImage = data.getData();  
         String[] filePath = {  
           MediaStore.Images.Media.DATA  
         };  
         Cursor c = this.getContentResolver().query(selectedImage, filePath, null, null, null);  
         c.moveToFirst();  
         int columnIndex = c.getColumnIndex(filePath[0]);  
         String picturePath = c.getString(columnIndex);  
         c.close();  
         Bitmap thumbnail = (BitmapFactory.decodeFile(picturePath));  
         Log.d("path of image", picturePath + "");  
         imageString = getStringImage(thumbnail);  
         ivproof.setImageBitmap(thumbnail);  
         // Toast.makeText(ctx,"Image="+imageString,Toast.LENGTH_SHORT).show();  
         btproof.setText("Uploaded");  
       } else {  
         Toast.makeText(this, "Something went wrong...", Toast.LENGTH_SHORT).show();  
       }  
     }  
     @Override  
     protected void onPause() {  
       super.onPause();  
       if (camera != null) {  
         camera.release(); // release the camera for other applications  
         camera = null;  
       }  
     }  

that 's all .
