Question

有谁可以帮助我，为什么我不能运行这个简单的应用程序，它是在Udemy教程，我已经检查了很多次，就像在教程中一样

    package com.example.hp250.actions;

    import android.net.Uri;
    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.view.View;
    import java.lang.reflect.InvocationTargetException;

  public class MainActivity extends AppCompatActivity {

  @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

public void OpenApp(View view) {

    Intent intent=new Intent(Intent.ACTION_VIEW);
    intent.setData(Uri.parse("market://details?id=com.soundcloud.android"));
    startActivity(intent);


  }
}

log cat：

Answer 1

Caused by: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=market://details?id=com.soundcloud.android }

您正在设备或模拟器上运行您的应用，该设备或模拟器缺少Play商店或处理market://details的{{1}} Uri值的任何其他活动。
