报错：

android.os.FileUriExposedException: file:///storage/emulated/0/photo.jpeg exposed beyond app through ClipData.Item.getUri()

解决

public class MainActivity extends AppCompatActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

//加 StrictMode

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {

StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();

StrictMode.setVmPolicy(builder.build());

}

}

public void openImage(View view) {

String path = "/storage/sda1/u=969646844,1823052119&fm=72.jpg";

File file = new File(path);

if (file.exists()) {

Uri uri = Uri.fromFile(file);

Intent intent = new Intent();

intent.setAction(Intent.ACTION_VIEW);

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);

intent.setDataAndType(uri, "image/jpeg");

startActivity(intent);

}else{

Toast.makeText(this, "图片不存在", Toast.LENGTH_SHORT).show();

}

}
