ContentManager

Library for getting photos, videos or files of any type from a device gallery, external storage, cloud(Google Drive, Dropbox and etc) or camera. With asynchronous load from the cloud and fixed bugs for some problem devices like Samsung or Sony.

Download

Download via Gradle:

compile 'com.github.stfalcon:contentmanager:0.5'

or Maven:

<dependency>
  <groupId>com.github.stfalcon</groupId>
  <artifactId>contentmanager</artifactId>
  <version>0.5</version>
  <type>pom</type>
</dependency>

Migration to version 0.5

In version 0.5 we have removed callback onLoadContentProgress(int loadPercent)(because it is very hard to calculate loadPercent correctly) and replaced it with callback onStartContentLoading() to handle a start of loading content. So if you are using ContentManager previous version, you need to make some correction after updating ContentManager version to 0.5. Also, we have added new cool feature: picking files with any types.

Usage

Add the folowing permission to AndroidManifest.xml:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Implement callback interface:

public class MainActivity extends AppCompatActivity implements ContentManager.PickContentListener {

Then implement PickContentListener methods:

/**
* Success result callback
*
* @param uri         Content uri
* @param contentType If you pick content can be Image or Video, if take - only Image
*/
@Override
public void onContentLoaded(Uri uri, String contentType) {
   if (contentType.equals(ContentManager.Content.IMAGE.toString())) {
       //You can use any library for display image Fresco, Picasso, ImageLoader
       //For sample:
       ImageLoader.getInstance().displayImage(uri.toString(), ivPicture);
   } else if (contentType.equals(ContentManager.Content.FILE.toString())) {
       //handle file result
       tvUri.setText(uri.toString());
   }
}
        
/**
* Call when loading started
*/
@Override
public void onStartContentLoading() {
  //Show loader or something like that
  progressBar.setVisibility(View.VISIBLE);
}

/**
* Call if have some problem with getting content
*
* @param error message
*/
@Override
public void onError(String error) {
  //Show error
}

/**
* Call if user manual cancel picking or taking content
*/
@Override
public void onCanceled() {
  //User canceled
}

Declare field:

private ContentManager contentManager;

Create instance where "this" is your activity:

contentManager = new ContentManager(this, this);

Override onActivityResult method of activity. It is needed for handling the result:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  super.onActivityResult(requestCode, resultCode, data);
  contentManager.onActivityResult(requestCode, resultCode, data);
}

Override onRequestPermissionsResult method to handle realtime permissions:

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    contentManager.onRequestPermissionsResult(requestCode, permissions, grantResults);
}

Override onSaveInstanceState, onRestoreInstanceState. It is needed for fixing bugs with some Samsung and Sony devices when taking photo in a landscape mode:

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
  super.onRestoreInstanceState(savedInstanceState);
  contentManager.onRestoreInstanceState(savedInstanceState);
}

@Override
protected void onSaveInstanceState(Bundle outState) {
  super.onSaveInstanceState(outState);
  contentManager.onSaveInstanceState(outState);
}

Pick image:

contentManager.pickContent(ContentManager.Content.IMAGE);

Pick video:

contentManager.pickContent(ContentManager.Content.VIDEO);

Pick file:

contentManager.pickContent(ContentManager.Content.FILE);

Take photo from camera:

contentManager.takePhoto();

Thanks to @coomar2841 and his Android Multipicker Library. We peeked at him some points in the implementation of picking files.
