Android java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()
E/AndroidRuntime(7200): Uncaught handler: thread Thread-8 exiting due to uncaught exception
E/AndroidRuntime( 7200): java.lang.RuntimeException: Can‘t create handler inside thread that has not called Looper.prepare()
原因是非主线程中默认没有创建Looper对象，需要先调用Looper.prepare()启用Looper。
解决办法：
public void sendJson2Server(final JSONObject mJs) {
Handler mHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
// TODO Auto-generated method stub
super.handleMessage(msg);
PushServiceEx.sendPublic(mTopicServer, mJs.toString());
System.out.println(mJs.toString());
}
};
mHandler.sendEmptyMessageDelayed(0, 5000);
// PushServiceEx.sendPublic(mTopicServer, mJs.toString());
}
new Thread() {
public void run() {
Looper.prepare();
mPst.startPushService();
mPst.sendJson2Server(qJson);//上线发消息给server
Looper.loop();
}
}.start();
加上上面红色两行。
