我已经尝试过此代码,但我没有看到我的帐户中共享的照片。

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);

Google+应用仅支持content:// URIs。为此,您需要使用MediaStore API。

 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");

在代码中集成ForGooglePlus活动,并为其添加URL(imageUrl),描述(描述文本)和contentUrl(URL)。 注意:波纹管代码也适用于我的应用程序。

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();

我也在google上发布图片通过android使用意图我正在拍摄设备的屏幕截图并在google plus上发布,我使用你的代码我得到异常FileNotFoundException()并且你提到使用绝对路径我得到了错误, 对于String类型,方法getAbsolutePath()未定义 我的代码如下 请建议我修改代码

不要使用绝对路径。

OnActivityResult()在从相机捕获图像后使用此功能。

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);

这对我有用。

HEy Deepika您收到文件或发现异常,因为您编码的方式设备上没有google plus应用程序只是为了从设备启动本机应用程序

仅当本机ap存在时才会起作用

另外就是google plus sdk这是一个小jar文件,可以共享图像

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

您可以使用以下api分享图片。有关详细步骤,请查看教程

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);
        }
    }
}
