[英]App Crashing on intent start with google maps
Java code for map activity 地图活动的Java代码
package com.schweigert.drinkingbuddy;
import android.app.Activity;
import android.os.Bundle;
public class BarMaps extends Activity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.barmaps);
}
}
XML Code XML代码
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.MapFragment" >
</fragment>
Java code that starts intent 开始意图的Java代码
maps.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View v) {
Intent openMap = new Intent("com.schweigert.drinkingbuddy.BarMaps");
startActivity(openMap);
}
});
When i am running this code on my emulator i have set up on my computer it brings up the "This app wont run unless you update Google Play services. But when i run it on a physical device it just times out and says that the app has stopped working.Why am i getting such a difference in errors between my emulator and physical device? 当我在模拟器上运行此代码时,我已经在计算机上进行了设置,它会显示“除非您更新Google Play服务,否则此应用程序将无法运行。但是当我在物理设备上运行该应用程序时,它将超时并说该应用程序已停止工作。为什么模拟器和物理设备之间的错误有如此大的区别?
Edit: 编辑:
package com.schweigert.drinkingbuddy;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.EditText;
public class StartingPoint extends Activity {
double numDrinks;
int counter;
EditText standardDrinks;
Button bacIntent, maps, drinks;
TextView display;
Bundle testBundle;
@Override
protected void onCreate(Bundle testBundle) {
super.onCreate(testBundle);
setContentView(R.layout.activity_starting_point);
counter = 0;
bacIntent = (Button) findViewById(R.id.bacIntent);
maps = (Button) findViewById(R.id.Maps);
drinks = (Button) findViewById(R.id.drinks);
bacIntent.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View v){
try{
Intent openBac = new Intent("com.schweigert.drinkingbuddy.BloodAlcoholContent");
startActivity(openBac);
}
catch(Exception e)
{
display.setText("my d" + e);
}
}
});
maps.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
try{
Intent openMap = new Intent("com.schweigert.drinkingbuddy.MainActivity");
startActivity(openMap);
}
catch(Exception e){
display.setText("my d"+ e);
}
}
});
drinks.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
try{
Intent openDrinkMenu = new Intent("com.schweigert.drinkingbuddy.DrinkType");
startActivity(openDrinkMenu);
}
catch(Exception e){
display.setText("my d:" + e);
}
}
});
}
}
So i had a try catch that was interacting with a textview that didn't exist anymore and then i had my manifest set up incorrectly. 因此,我尝试将其与不再存在的textview进行交互,然后我的清单设置不正确。 Thanks for the help Shivan.
感谢Shivan的帮助。
