“resolveUri在错误的位图uri上失败：content：// media / external / images / media / 49644”我无法查看图像

Question

hello I'm a beginner in developing android apps.I've been doin a contacts app. This is my java code where im unable to display image on my gui after selecting image from gallery. Ive tested in ANDROID KITKAT IT DOESNT SHOW IMAGE. But this code works successfully on ANDROID ICECREAM SANDWICH,IT DISPLAYS IMAGE AFTER CHOOSING FROM gallery.

contactimageview.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
    Intent intent= new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent,"select image"),1);
   }
});
}

public void onActivityResult(int reqCode,int resCode,Intent data) {
    if (resCode == RESULT_OK) {
        if (reqCode==1){
            imageUri = data.getData();
            contactimageview.setImageURI(data.getData());
      }}
      }

after i select the image i get the following log as below I think there is a problem in onActivityResult method code.

Answer 1

您需要将权限<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>到清单文件中。
