Uploading image from Android to GCS
Fixed for Android:
Android Studio config:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile files('libs/android-support-v4.jar')
compile files('google-play-services.jar')
compile 'com.wu-man:android-oauth-client:0.0.3'
compile 'com.google.apis:google-api-services-storage:v1-rev17-1.19.0'
compile(group: 'com.google.api-client', name: 'google-api-client', version:'1.19.0'){
exclude(group: 'com.google.guava', module: 'guava-jdk5')
}
}
AndroidManifiest:
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"></uses-permission>
Main implementation:
new AsyncTask(){
@Override
protected Object doInBackground(Object[] params) {
try {
CloudStorage.uploadFile("bucket-xxx", "photo.jpg");
} catch (Exception e) {
if(DEBUG)Log.d(TAG, "Exception: "+e.getMessage());
e.printStackTrace();
}
return null;
}
}.execute();

Hpsaturn's answer worked for me. He missed to answer a few points. How to get service account id and p12 file. For getting these 2, open console.developers.google.com and choose your project. Enable Cloud Storage API. You see a message to create credentials. Go to credentials in API manager and create credential by selecting Service account key and follow the details in image. You will get the service account id and p12 file from this screen.
Hpsaturn also missed to mention AppData, which is your custom Application class defined in manifest. For everyone's convenience, I am attaching the complete CloudStorage class here.

btb, I used only following dependency in the gradle.
compile 'com.google.apis:google-api-services-storage:+'
Since no one is answering this question, let me update the way I solved this problem. I ended up following this https://github.com/pliablematter/simple-cloud-storage project.
I could upload Pictures/Videos to GCS from my Android app.
This snippet of code works for me great for uploading files from Android directly to GCS.
File file = new File(Environment.getExternalStorageDirectory(), fileName);
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
FileBody filebody = new FileBody(file,ContentType.create(mimeType), file.getName());
MultipartEntityBuilder multipartEntity = MultipartEntityBuilder.create();
multipartEntity.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
multipartEntity.addPart("file", filebody);
httppost.setEntity(multipartEntity.build());
System.out.println( "executing request " + httppost.getRequestLine( ) );
try {
HttpResponse response = httpclient.execute( httppost );
Log.i("response", response.getStatusLine().toString());
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
httpclient.getConnectionManager( ).shutdown( );
MultipartEntityBuilder class is not included into android standard libraries so you need to download httpclient and include into your project.
