everyone. I am new to android. Recently, I tried to learn how to extend Application, but there is a strange problem. I have tried a lot of methods, but still can not solve it. So, thanks in advance if anyone can help me.
The code section is like this:
package com.example.xw.myfirstapplication;
import android.app.Application;
/**
* Created by Administrator on 2016/8/26.
*/
public class MyApplication extends Application {
public static MyApplication mApplication;
@Override
public void onCreate(){
super.onCreate();
mApplication = this;
}
public static MyApplication getMyApplication(){
return mApplication;
}
}
And, Manifest.xml is like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.xw.myfirstapplication"
>
<uses-sdk
android:minSdkVersion="19"
android:targetSdkVersion="24" />
<uses-permission android:name="android.permission.INTERNET"/>
<application android:name="com.example.xw.myfirstapplication.MyApplication"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
>
<!--<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>-->
<!--<uses-permission android:name="android.permission.INTERNET"></uses-permission>-->
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!--<activity android:name="testNewTech.DisplayMessageActivity" />
<activity android:name="testNewTech.NotificationActivity"></activity>-->
</application>
</manifest>
But, when I run the code, something happens very quickly, like this:
In addition: 1. I tried not to use extended Application but default Application, everything is good.
- I add Log.v("MainActivity", "start onCreate"); in method onCreate() of class MainActivity. But, there is nothing in logcat, so I think the method onCreate() of class MainActivity is not processed.
So, anyone has any advice? Thank you so much!
