ACCESSAndroid Http请求失败解决智

1、MainActivity.java 文件中之onCreate方法改成为如下:

@SuppressLint(“NewApi”)

@Override
protected void onCreate(Bundle
savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
StrictMode.setThreadPolicy(new
StrictMode.ThreadPolicy.Builder()
.detectDiskReads().detectDiskWrites().detectNetwork()
.penaltyLog().build());
StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()

.detectLeakedSqlLiteObjects().penaltyLog().penaltyDeath()

}

2、AndroidManifest.xml ACCESS里面的manifest加入配置

<uses-permission
android:name=”android.permission.ACCESS_NETWORK_STATE” />
 <uses-permission
android:name=”android.permission.WRITE_EXTERNAL_STORAGE” />
 <uses-permission android:name=”android.permission.INTERNET” />
