如何在 Android 中共享具有意图的图像位图

Question

(这个问题不是重复的！

如何通过意图共享图像？

我试过这个

位图的 Android 共享意图 - 是否可以在共享之前不保存它？

如何使用位图将图像分享到社交媒体？

与网址共享图像 安卓共享意图

但仅适用于模拟器，不适用于实际手机，并出现以下代码错误：

//b method : convert inputstream to bitmap
String bitmapPath = MediaStore.Images.Media.insertImage(getContentResolver(), b(inputStream) ,"title", null);

完整代码 ：

InputStream is = getAssets().open(imageName.getText().toString());
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
String path = Environment.getExternalStorageDirectory()+"/" + APP_NAME()+"/pictures/"+ls+"/" ;
new File(path).mkdirs();
String fileName = System.currentTimeMillis() + imageName.getText().toString().replace("pic/" , "");
FileOutputStream fileOutputStream = new FileOutputStream(new File(path+fileName));
fileOutputStream.write(buffer);
fileOutputStream.close();
InputStream inputStream = new FileInputStream(new File(path+fileName));
String bitmapPath = MediaStore.Images.Media.insertImage(getContentResolver(), b(inputStream) ,"title", null);
Uri bitmapUri = Uri.parse(bitmapPath);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM , bitmapUri);
startActivity(intent);

//Intent intent = new Intent(android.content.Intent.ACTION_SEND);
//intent.putExtra(Intent.EXTRA_STREAM, bitmapUri);
//intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
//intent.setType("image/*");
//startActivity(intent);

我的问题通过对代码进行一个小改动来解决：

Uri bitmapUri = Uri.parse (new File (path + fileName) .toString ());

完整代码 ：

InputStream is = getAssets().open(imageName.getText().toString());
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
String path = Environment.getExternalStorageDirectory()+"/" + APP_NAME()+"/pictures/"+ls+"/" ;
new File(path).mkdirs();
String fileName = System.currentTimeMillis() + imageName.getText().toString().replace("pic/" , "");
FileOutputStream fileOutputStream = new FileOutputStream(new File(path+fileName));
fileOutputStream.write(buffer);
fileOutputStream.close();
//InputStream inputStream = new FileInputStream(new File(path+fileName));
//String bitmapPath = MediaStore.Images.Media.insertImage(getContentResolver(),b(inputStream) ,"title", null); // comment this line
Uri bitmapUri = Uri.parse(new File(path+fileName).toString()); //changed
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM , bitmapUri);
startActivity(intent);
if (new File(path+fileName).exists()){
    new File(path+fileName).delete();
}
