Question

我只是想在我的应用中加载Google地图应用，但它总是会收到一条消息，Unfortunately, the app has stopped.

我也搜索了其他stackoverflow的答案，但没有得到它为什么每次点击Show Map按钮时强行关闭的原因。

我的代码是：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.himanshu.intents.MainActivity" >

<Button
    android:id="@+id/button3"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/button2"
    android:layout_below="@+id/button2"
    android:layout_marginTop="14dp"
    android:onClick="onClickSM"
    android:text="Show Map" />

</RelativeLayout>

MainActivity文件：

public class MainActivity extends Activity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
 }
 public void onClickSM(View v) {
    Intent i = new Intent (android.content.Intent.ACTION_VIEW);
    i.setData(Uri.parse("geo:<28.629404>,<77.086824>?q=<28.629404>,<77.086824>"));
    startActivity(i);
 }
}

Answer 1

首先，您尝试解析的geo:网址不是the documented and supported structures之一，超出了在cygery＆s;中注明的无效<和>之内答案。

其次，您的设备或模拟器上可能没有符合geo: Intent的地图应用程序。

Answer 2

删除URI中的<和>：

i.setData(Uri.parse("geo:28.629404,77.086824?q=28.629404,77.086824"));

Intent中的geo无法在Android应用中运行
