在做接口優(yōu)化的時候發(fā)現(xiàn)APP 的Application 的onCreate方法被執(zhí)行了好幾次，導(dǎo)致在onCreate里面做了一些初始化的操作被重復(fù)執(zhí)行了多次，打斷點無果，但抓包卻真的存在，這令我十分尷尬。。。事后才發(fā)現(xiàn)有一些第三方組件，它們是單獨開了一個進(jìn)程
解決辦法根據(jù)進(jìn)程名進(jìn)行初始化過濾，Application 的onCreate 里只初始化一次。
解決方法一：
判斷當(dāng)前進(jìn)程是主進(jìn)程才執(zhí)行初始化代碼.
Android避免多進(jìn)程Application onCreate中初始化代碼執(zhí)行多次

if (TextUtils.equals(getCurrentProcessName(this), getPackageName())) {
         init();//判斷成功后才執(zhí)行初始化代碼
}

private String getCurrentProcessName(Context context) {
        int pid = android.os.Process.myPid();
        ActivityManager mActivityManager = (ActivityManager) context
                .getSystemService(Context.ACTIVITY_SERVICE);
        for (ActivityManager.RunningAppProcessInfo appProcess : mActivityManager
                .getRunningAppProcesses()) {
            if (appProcess.pid == pid) {
                return appProcess.processName;
            }
        }
        return null;
}

解決方法二：
內(nèi)容摘自：Android多進(jìn)程時Application初始化問題，大坑

public class MyApplication extends Application {
    private final static String PROCESS_NAME = "com.test";
    private static MyApplication myApplication = null;
 
    public static MyApplication getApplication() {
        return myApplication;
    }
 
    /**
     * 判斷是不是UI主進(jìn)程，因為有些東西只能在UI主進(jìn)程初始化
     */
    public static boolean isAppMainProcess() {
        try {
            int pid = android.os.Process.myPid();
            String process = getAppNameByPID(MyApplication.getApplication(), pid);
            if (TextUtils.isEmpty(process)) {
                return true;
            } else if (PROCESS_NAME.equalsIgnoreCase(process)) {
                return true;
            } else {
                return false;
            }
        } catch (Exception e) {
            e.printStackTrace();
            return true;
        }
    }
 
    /**
     * 根據(jù)Pid得到進(jìn)程名
     */
    public static String getAppNameByPID(Context context, int pid) {
        ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        for (android.app.ActivityManager.RunningAppProcessInfo processInfo : manager.getRunningAppProcesses()) {
            if (processInfo.pid == pid) {
                return processInfo.processName;
            }
        }
        return "";
    }
 
    @Override
    public void onCreate() {
        super.onCreate();
 
        myApplication = this;
 
        if (isAppMainProcess()) {
            //do something for init
        }
    }
