我正在使用ACTION_SEND在Facebook上分享图片,但它无法使用.code就在这里
try {
File myFile = new File("/mnt/sdcard/DCIM/100MEDIA/aa.jpg");
MimeTypeMap mime = MimeTypeMap.getSingleton();
String ext = myFile.getName().substring(
myFile.getName().lastIndexOf(".") + 1);
String type = mime.getMimeTypeFromExtension(ext);
Intent sharingIntent = new Intent(
"android.intent.action.SEND");
sharingIntent.setType(type);
sharingIntent.putExtra("android.intent.extra.STREAM",
Uri.fromFile(myFile));
startActivity(Intent.createChooser(sharingIntent,
"Share using"));
} catch (Exception e) {
Toast.makeText(getBaseContext(), e.getMessage(),
Toast.LENGTH_SHORT).show();
}
但它出现错误“无法上传”
我正在使用此链接(“Share Image via android app using ACTION_SEND not working”)

请尝试这种方式,希望这有助于您解决问题。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try {
File myFile = new File(Environment.getExternalStorageDirectory()+"/100MEDIA/aa.jpg");
Intent sharingIntent = new Intent("android.intent.action.SEND");
sharingIntent.setType(getMimeType(myFile.getPath()));
sharingIntent.putExtra("android.intent.extra.STREAM",Uri.fromFile(myFile));
startActivity(Intent.createChooser(sharingIntent,"Share using"));
} catch (Exception e) {
Toast.makeText(getBaseContext(), e.getMessage(),Toast.LENGTH_SHORT).show();
}
}
public String getMimeType(String filePath) {
String type = null;
String extension = getFileExtensionFromUrl(filePath);
if (extension != null) {
MimeTypeMap mime = MimeTypeMap.getSingleton();
type = mime.getMimeTypeFromExtension(extension);
}
return type;
}
public String getFileExtensionFromUrl(String url) {
int dotPos = url.lastIndexOf('.');
if (0 <= dotPos) {
return (url.substring(dotPos + 1)).toLowerCase();
}
return "";
}
