Android中全局Application的onCreate屢次調用問題

 通常來講Application的onCreate方法只會執行一次，

若是應用中採用多進程方式，oncreate方法會執行屢次，根據不一樣的進程名字進行不一樣的初始化:

        String processName = getProcessName(this, android.os.Process.myPid());        
        if (processName != null) {            
        boolean defaultProcess = processName.equals(Constants.REAL_PACKAGE_NAME);            
        if (defaultProcess) {
                initAppForMainProcess();
         } else if (processName.contains(":webbrowser")) {
                
         } else if (processName.contains(":wallet")) {
         
         }
       }

/**
     * @return null may be returned if the specified process not found     */
    public static String getProcessName(Context cxt, int pid) {
        ActivityManager am = (ActivityManager) cxt.getSystemService(Context.ACTIVITY_SERVICE);
        List<RunningAppProcessInfo> runningApps = am.getRunningAppProcesses();       
         if (runningApps == null) {            
         return null;
        }        
        for (RunningAppProcessInfo procInfo : runningApps) {            
            if (procInfo.pid == pid) {               
                 return procInfo.processName;
            }
        }        
        return null;
    }

新增一種獲取運行進程名稱的方案：

public static String getProcessName() {

  try {

    File file = new File("/proc/" + android.os.Process.myPid() + "/" + "cmdline");

    BufferedReader mBufferedReader = new BufferedReader(new FileReader(file));

    String processName = mBufferedReader.readLine().trim();

    mBufferedReader.close();

    return processName;

  } catch (Exception e) {

    e.printStackTrace();

    return null;

  }

}
