1. 目的

不進行攔截賬戶服務

2. 識別賬戶服務

主要在bing-service中判斷action是否匹配ACTION_AUTHENTICATOR_INTENT

import static android.accounts.AccountManager.ACTION_AUTHENTICATOR_INTENT;

    if ("android".equals(callerApp)
        && intent != null  && ACTION_AUTHENTICATOR_INTENT.equals(intent.getAction())
        // 當前是否有使用者操作行為
        && isUserTouchActive()) {
        if (DEBUG) Slog.d(TAG, "bind Account service :" + targetApp + " from " + callerApp);
        return true;
    }
 

3. 應用層介面

    public static HashMap<String, String> getAccountAuthenticators(Context context) {
        PackageManager pm = context.getPackageManager();

        HashMap<String, String> accountList = new HashMap<String, String>();
        Intent intent = new Intent("android.accounts.AccountAuthenticator");

        List<ResolveInfo> resolveInfoList = pm.queryIntentServices(intent, PackageManager.GET_DISABLED_COMPONENTS);

        for (ResolveInfo resolveInfo : resolveInfoList) {
            ServiceInfo packinfo = resolveInfo.serviceInfo;
            if ((packinfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) == 0) {
                accountList.put(packinfo.packageName, packinfo.name);
                Log.d(TAG, "getAccountAuthenticators packageName = " + packinfo.packageName + ", name " + packinfo.name);
            }
        }
        return accountList;
    }
