Application中的初始化

来源：互联网发布：linux mint 18 编辑：程序博客网时间：2024/06/06 03:00

每个进程开启走Application中的onCreate方法，保证一切进程在主线程中初始化，判断是否为主线程的方法如下：`public class HuaqianApplication extends Application {

public static HuaqianApplication app;@Overridepublic void onCreate() {    super.onCreate();    if (quickStart()) {        return;    }    if (isMainProcess()) {    //初始化操作         }}public boolean quickStart() {    if (StringUtil.contains(getCurProcessName(this), ":mini")) {        return true;    }    return false;}    private boolean isMainProcess() {    ActivityManager am = ((ActivityManager) getSystemService(Context.ACTIVITY_SERVICE));    List<RunningAppProcessInfo> processInfos = am.getRunningAppProcesses();    String mainProcessName = getPackageName();    int myPid = Process.myPid();    for (RunningAppProcessInfo info : processInfos) {        if (info.pid == myPid && mainProcessName.equals(info.processName)) {            return true;        }    }    return false;}}
