Mediastore.images.media.InsertiMage在三星平板电脑上失败

Question

我的代码只会在三星Galaxy平板电脑上崩溃（例如SM-P601、Android4.4.2)。

崩溃的代码是这一行：

String path = MediaStore.Images.Media.insertImage(context.getContentResolver(), null, "ShareImage", null);

另一个失败的代码只是在OnClick方法中：

Bitmap bm = Bitmap.createBitmap(128, 128, Bitmap.Config.ARGB_8888);
String path = MediaStore.Images.Media.insertImage(MainActivity.this.getContentResolver(), bm, "ShareImage", null);
Log.d("tag", path);

null

public static void fixMediaDir() {
    File sdcard = Environment.getExternalStorageDirectory();
    if (sdcard == null) { return; }
    File dcim = new File(sdcard, "DCIM");
    if (dcim == null) { return; }
    File camera = new File(dcim, "Camera");
    if (camera.exists()) { return; }
    camera.mkdir();
}
