Upload files such as(image,video,docs) to my drive folder

basically I am creating an app where users can upload his/her files on drive by creating folders. Here I have been Successfully created a folder now the issue wt I am facing is how to upload files on that folder which the user just created.where the user can select multiple images, videos, docs, etc. For the select purpose, I have chosen intent but am not able to get how to upload it. Here's the code wt I have done till now.
For Creating Folder I used this method now I want to upload files in this folder please let me know
if (mDriveServiceHelper == null) {
return;
}
mDriveServiceHelper.createFolder("FolderNew", null)
.addOnSuccessListener(new OnSuccessListener<GoogleDriveFileHolder>() {
#Override
public void onSuccess(GoogleDriveFileHolder googleDriveFileHolder) {
Gson gson = new Gson();
Log.d(TAG, "onSuccess: " + gson.toJson(googleDriveFileHolder));
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.d(TAG, "onFailure: " + e.getMessage());
}
});
For Picking Up Images And Videos
Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), PICK_IMAGE_MULTIPLE);

Pick image from Gallery - File not found when running newer Android versions

I am working on a address book like Android SDK 14+ app. The users should be able to pick an image from the Gallery to add it to a contact entry.
Running the following code to pick and copy the image is no problem in API 14-20 but does not work in API 21+. The file is not found anymore:
protected void pickFoto() {
if (filePermissionsRequired()) {
askForFilePermissions(new PermissionRequestCompletionHandler() {
#Override
public void onPermissionRequestResult(boolean permissionGranted) {
if (permissionGranted)
addOrEditReceipt();
}
});
return;
}
Intent pickPhotoIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickPhotoIntent , PICK_FOTO_ACTION);
}
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (resultCode == Activity.RESULT_OK) {
switch (requestCode) {
...
case PICK_FOTO_ACTION: {
Uri imageUri = intent.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(imageUri, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String filePath = cursor.getString(columnIndex);
cursor.close();
File imgFile = new File(filePath);
if (imgFile.exists())
// use the file...
else
Toast.makeText(this, "Image file not found", Toast.LENGTH_LONG).show();
break;
}
}
public interface PermissionRequestCompletionHandler {
void onPermissionRequestResult(boolean permissionGranted);
}
private PermissionRequestCompletionHandler permissionRequestCompletionHandler;
public boolean filePermissionsRequired() {
if (Build.VERSION.SDK_INT >= 23)
return checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED;
else
return false;
}
public boolean askForFilePermissions(PermissionRequestCompletionHandler completionHandler) {
if (Build.VERSION.SDK_INT >= 23) {
permissionRequestCompletionHandler = completionHandler;
boolean hasPermission = this.checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED;
if (!hasPermission) {
this.requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE}, 1);
return true;
}
}
permissionRequestCompletionHandler = null;
return false;
}
The app has runtime permissions to access the Gallery. So what am I doing wrong? How to access the file on newer API versions?
}

try below code to open the camera and getting result:
File file = new File(Environment.getExternalStorageDirectory() + "/DCIM/", "image" + System.currentTimeMillis() + ".png");
Uri imageUri = Uri.fromFile(file);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, PICK_FOTO_ACTION);
for getting result :
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
switch (requestCode) {
case PICK_FOTO_ACTION: {
Uri imageUri = imageUri;
File imgFile = new File(imageUri.getPath());
if (imgFile.exists())
// use the file...
else
Toast.makeText(this, "Image file not found", Toast.LENGTH_LONG).show();
break;
}
}
}
for getting actual path from uri :
public String getPath(Uri uri)
{
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if (cursor == null) return null;
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String s=cursor.getString(column_index);
cursor.close();
return s;
}
remove unwanted uri part :
public String RemoveUnwantedString(String pathUri){
//pathUri = "content://com.google.android.apps.photos.contentprovider/-1/2/content://media/external/video/media/5213/ORIGINAL/NONE/2106970034"
String[] d1 = pathUri.split("content://");
for (String item1:d1) {
if (item1.contains("media/")) {
String[] d2 = item1.split("/ORIGINAL/");
for (String item2:d2) {
if (item2.contains("media/")) {
pathUri = "content://" + item2;
break;
}
}
break;
}
}
//pathUri = "content://media/external/video/media/5213"
return pathUri;
}

For versions 21 and higher you can do this , you need to add a condition to check the SDK version for this. Exectute this code in the API 21+ condition block.
String wholeID = DocumentsContract.getDocumentId(imageUri );
String id = wholeID.split(":")[1];
String sel = MediaStore.Images.Media._ID + "=?";
cursor =
getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
projection, sel, new String[]{ id }, null);
try
{
int column_index = cursor
.getColumnIndex(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
path = cursor.getString(column_index).toString();
cursor.close();
}
catch(NullPointerException e) {
}

Call the Gallery with belo code
public static final int SELECT_IMAGE_FROM_GALLERY_CODE = 701;
public static void callGallery(Activity activity) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);

Storing image to internal storage

I want to store my images to internal storage, I searched google and stackoverflow but couldn't get it done, Here is my code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
imageView = (ImageView) findViewById(R.id.ss);
tv = (TextView) findViewById(R.id.tv);
// Firebase.setAndroidContext(this);
//Firebase ref = new Firebase(FIREBASE_URL);
Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data)
{
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
bitmap = BitmapFactory.decodeResource(getResources(),
RESULT_LOAD_IMAGE);
// Find the SD Card path
File filepath = Environment.getExternalStorageDirectory();
// Create a new folder in SD Card
File dir = new File(filepath.getAbsolutePath()
+ "/Save Image Tutorial/");
dir.mkdirs();
// Create a name for the saved image
File file = new File(dir, "myimage.png");
// Show a toast message on successful save
Toast.makeText(MainActivity.this, "Image Saved to SD Card",
Toast.LENGTH_SHORT).show();
try {
output = new FileOutputStream(file);
// Compress into png format image from 0% - 100%
bitmap.compress(Bitmap.CompressFormat.PNG, 100, output);
output.flush();
output.close();
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
// drawView.load_pic(picturePath);
}
}
I want to get an image from the gallery and store it to internal storage but in this code, it is only saving the name of the file in the directory. If someone could help me to solve this.

You could use FileOutputStream to store your bitmap. After getting the bitmap from gallery, FileOutputStream out = null;
try {
out = new FileOutputStream("fileName"); //Enter the desired filename
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (out != null) {
out.close();
}
} catch (Exception e) {
e.printStackTrace();
}
}

you are writing Image file on external storage
File filepath = Environment.getExternalStorageDirectory();
so check that you have mention proper permission in android manifest to write data on SD card
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
and also get the bitmap from selected path
Bitmap bitmap = BitmapFactory.decodeFile(picturePath);
instead of
bitmap = BitmapFactory.decodeResource(getResources(),
RESULT_LOAD_IMAGE);
RESULT_LOAD_IMAGE is request code not resource id of selected image

OnChoose Code
chooseimage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (Build.VERSION.SDK_INT >= 23){
boolean result= Utility.checkPermission(getActivity());
if(result) {
galleryIntent();
}
}
else {

// Start new activity with the LOAD_IMAGE_RESULTS to handle back the results when image is picked from the Image Gallery.
startActivityForResult(i,LOAD_IMAGE_RESULTS); //LOAD_IMAGE_RESULTS
}
}
});

android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, GALLERY_REQUEST);
File file = getFileStreamPath("QuickPlayBG.png");
if (file.exists()) {
QPBackground.setImageBitmap(getThumbnail("QuickPlayBG.png"));
} else {
String uri21 = "#drawable/bg_green";
int imageResource21 = getResources().getIdentifier(uri21, null, getPackageName());
QPBackground.setBackgroundResource(imageResource21);
}
}
This sends you here:
protected void onActivityResult (int requestCode, int resultCode, Intent data)
{
Uri selectedImageUri;
if (requestCode == GALLERY_REQUEST && resultCode == RESULT_OK && null !=
data) {
selectedImageUri = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImageUri,
filePathColumn, null, null, null);
cursor.moveToFirst();
cursor.close();
}
try {
Bundle extras = data.getExtras();
Bitmap photo = extras.getParcelable("data");
saveBGFile(photo);
} catch (Exception e) {
String errorMessage = "Make your mind up mate!";
Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
toast.show();
}
try {
saveQPConfig();
} catch (IOException e) {
String errorMessage = "Saving failed";
Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
toast.show();
}
}
Which saves the file, using saveBGFile:
public void saveBGFile(Bitmap image) {
FileOutputStream out = null;
String filename = "QuickPlayBG.png";
try {
out = new FileOutputStream(filename);
image.compress(Bitmap.CompressFormat.PNG, 100, out);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (out != null) {
out.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
The issue is with this line only:
QPBackground.setImageBitmap(getThumbnail("QuickPlayBG.png"));
It doesn't load anything. If I change "QuickPlayBG.png" to another filename that I am using in another part of my app, it loads fine. Both files are created using the same method. I verified that "QuickPlayBG.png" exists.
Compiler gives me the following hint:
E/﹕ ReadStreamToBuffer : Qmage Stream read error!! required length 12 bytes, but red 0 bytes
E/﹕ isQmage : input SkStreamRewindable length is less than Qmage minimum size : 0
I think it has to do with the way I am saving the image, but I cannot see the fault myself. What could be the problem, that it is not loading the image?
Edit:
Here is the getThumbnail method I am using (works for another filename):
public Bitmap getThumbnail(String filename) {
final Context context = this;
String fullPath = Environment.getExternalStorageDirectory().getAbsolutePath();
Bitmap thumbnail = null;
if (thumbnail == null) {
try {
File filePath = context.getFileStreamPath(filename);
FileInputStream fi = new FileInputStream(filePath);
thumbnail = BitmapFactory.decodeStream(fi);
} catch (Exception ex) {
Log.e("getThumbnail() !exist", ex.getMessage());
}
}
return thumbnail;
}

Use this short and sweet code for this. use intent of gallery.
1.declaire variable.
private static int RESULT_IMG = 1;
String imgString;
2.call intent of gallery on onclick of button.
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent, RESULT_LOAD_IMG);
3.onActivityResult to your code.
#Override
protected void onActivityResult(int requestCode, int responseCode, Intent data) {
super.onActivityResult(requestCode, responseCode, data);
try {
if (requestCode == RESULT_IMG && responseCode == RESULT_OK
&& null != data) {
Uri pickedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(pickedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imgString = cursor.getString(columnIndex);
cursor.close();
//set bitmap to your imageview
ImageView imgView = (ImageView) findViewById(R.id.imgView);
imgView.setImageBitmap(BitmapFactory.decodeFile(imgString));
} else {
Toast.makeText(this, "please select picture",Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
Toast.makeText(this, "error message", Toast.LENGTH_LONG)
.show();
}
}
