如何通过Android应用程序在谷歌加分享图像？

Question

I have already tried this code, but i didn't saw photo shared in my account.

File file = new File("sdcard/1346249742258.jpg");
String photoUri = null;
photoUri = file.getAbsolutePath();

Intent shareIntent = ShareCompat.IntentBuilder.from(this)
        .setText("Sharing an image on Google!").setType("image/jpeg")
        .setStream(Uri.parse(photoUri)).getIntent()
        .setPackage("com.google.android.apps.plus");
startActivity(shareIntent);

Answer 1

The Google+ app only supports content:// URIs . You will need to use the MediaStore API for this purpose.

 File tmpFile = new File("/path/to/image");
 final String photoUri = MediaStore.Images.Media.insertImage(
         getContentResolver(), tmpFile.getAbsolutePath(), null, null);

 Intent shareIntent = ShareCompat.IntentBuilder.from(this)
         .setText("Hello from Google+!")
         .setType("image/jpeg")
         .setStream(Uri.parse(photoUri))
         .getIntent()
         .setPackage("com.google.android.apps.plus");

Integrate ForGooglePlus Activity in your code and put URL(imageUrl) ,Description(description text) and contentUrl(URL) for the same. Note : bellow code also worked in my app.

public class ForGooglePlus extends Activity
{
    private String imageUrl, description, contentUrl;
    private Context mContext;
    private int REQUEST_FOR_GOOGLE_PLUS = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);

        mContext = this;
        imageUrl = getIntent().getStringExtra("URL");
        description = getIntent().getStringExtra("Description");
        contentUrl = getIntent().getStringExtra("contentUrl");

        if (isPackageInstalled("com.google.android.apps.plus", mContext)) {
            if (imageUrl == null) {
                imageUrl = "";
            }
            if (description == null) {
                description = "";
            }
            // Intent shareIntent = new PlusShare.Builder(this)
            // .setType("image/jpeg")
            // .setText(description)
            // .setStream(getUriFromUrl(imageUrl))
            // .setContentUrl(Uri.parse(contentUrl))
            // .getIntent();

            Uri uri = getUriFromUrl(imageUrl);
            if (uri != null) {
                Intent shareIntent = ShareCompat.IntentBuilder
                        .from(ForGooglePlus.this)
                        .setText(description + "\n" + contentUrl)
                        .setType("image/jpeg").setStream(uri).getIntent()
                        .setPackage("com.google.android.apps.plus");
                startActivityForResult(shareIntent, REQUEST_FOR_GOOGLE_PLUS);
            } else {
                Intent shareIntent = ShareCompat.IntentBuilder
                        .from(ForGooglePlus.this)
                        .setText(description + "\n" + contentUrl)
                        .setType("image/jpeg").getIntent()
                        .setPackage("com.google.android.apps.plus");
                startActivityForResult(shareIntent, REQUEST_FOR_GOOGLE_PLUS);
            }
        } else {
            Toast.makeText(mContext, "Application not found", Toast.LENGTH_LONG)
                    .show();
            finish();
        }
    }

    public Uri getUriFromUrl(String thisUrl) {
        try {

            Bitmap inImage = ImageLoader.getInstance().loadImageSync(thisUrl);
            ByteArrayOutputStream bytes = new ByteArrayOutputStream();
            inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
            String path = Images.Media.insertImage(
                    mContext.getContentResolver(), inImage, "Title", null);
            return Uri.parse(path);
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();

        }
        return null;
    }

    private boolean isPackageInstalled(String packagename, Context context) {
        PackageManager pm = context.getPackageManager();
        try {
            pm.getPackageInfo(packagename, PackageManager.GET_ACTIVITIES);
            return true;
        } catch (NameNotFoundException e) {
            return false;
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == REQUEST_FOR_GOOGLE_PLUS) {
            if (resultCode == RESULT_OK) {
                finish();
            } else {
                Toast.makeText(mContext,
                        mContext.getString(R.string.msg_gp_cancel),
                        Toast.LENGTH_LONG).show();
                finish();
            }
        }
    }

}

Answer 4

Don't use absolute path.

OnActivityResult() use this after capturing image from camera.

Uri photoUri = intent.getData();                
Intent shareIntent = ShareCompat.IntentBuilder.from(this)
                         .setText("Hello From Google+!")
                             .setType("image/jpeg")
                             .setStream(photoUri)
                             .getIntent()
                     .setPackage("com.google.android.apps.plus");
startActivity(shareIntent);

This is working for me.

Answer 5

HEy Deepika you are getting file nor found exception because that google plus app is not present on the device the way you have coded is just to start the native app from the device

it will work only if the native ap is actully present

otherway is to have google plus sdk which is small jar file with that you can share image

https://developers.google.com/+/mobile/android/

Answer 6

You can share image using below api's. For detailed steps check tutorial

http://androidsrc.net/integrating-google-plus-sign-in-into-your-android-application/

 /**
     * API to process media post request start activity with MIME type as video
     * and image
     */
    private void processShareMedia() {
        Intent photoPicker = new Intent(Intent.ACTION_PICK);
        photoPicker.setType("video/*, image/*");
        startActivityForResult(photoPicker, PICK_MEDIA_REQUEST_CODE);

    }

/**
 * Handle results for your startActivityForResult() calls. Use requestCode
 * to differentiate.
 */
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == PICK_MEDIA_REQUEST_CODE) {
        // If picking media is success, create share post using
        // PlusShare.Builder
        if (resultCode == RESULT_OK) {
            Uri selectedImage = data.getData();
            ContentResolver cr = this.getContentResolver();
            String mime = cr.getType(selectedImage);

            PlusShare.Builder share = new PlusShare.Builder(this);
            share.setText("Hello from AndroidSRC.net");
            share.addStream(selectedImage);
            share.setType(mime);
            startActivityForResult(share.getIntent(),
                    SHARE_MEDIA_REQUEST_CODE);
        }
    }
}
