我已经尝试过此代码，但我没有看到在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:// URI。MediaStore为此，您需要使用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");
将 ForGooglePlus Activity 集成到您的代码中，并将 URL(imageUrl) 、Description(description text) 和 contentUrl(URL) 放在相同的位置。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 {

}
}

我还使用意图通过android在google plus上发布图像我正在拍摄设备的屏幕截图并将其发布在google plus上，我使用你的代码我得到异常FileNotFoundException（）并且正如你提到使用绝对路径我得到错误，方法 getAbsolutePath() 对于 String 类型未定义我的代码在下面给出请建议我在代码中更正

谢谢你和问候尼丁
不要使用绝对路径。
OnActivityResult() 在从相机捕获图像后使用它。
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。
嘿，Deepika，您正在获取文件，也没有发现异常，因为设备上不存在该 google plus 应用程序，您编码的方式只是从设备启动本机应用程序
只有当本机 ap 确实存在时它才会起作用
其他方法是拥有 google plus sdk，这是一个小 jar 文件，您可以使用它共享图像
您可以使用以下 api 共享图像。详细步骤查看教程
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);
}
}
