PermissionDemo

簡介

3個步驟, 簡單解決 關於Android 6.0以上的權限問題, 有興趣 可以參考看看                               

取材自以下資源

跟前輩 Benson 學習的, 再次感謝                                  

使用步驟

1. 在 AndroidManifest中, 填上你需要的權限

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

2. 自定義一個Class, 在裡面也填上你需要的權限, 以及相關請求權限的方法                                     

public final class Global {

    public static final int PERMS_REQUEST_CODE = 200;

    /**
     * 你想開啟哪些權限
     * AndroidManifest中, 也要填上相關權限
     * */
    private static String[] perms = {

            "android.permission.READ_EXTERNAL_STORAGE",
            "android.permission.WRITE_EXTERNAL_STORAGE"

            /*  以下是 大部分的權限, 如果不知道該開啟哪個權限, 可以試試看先開啟大部分的權限, 然後再一個一個比對刪去
            "android.permission.ACCESS_WIFI_STATE",
            "android.permission.INTERNET",
            "android.permission.ACCESS_NETWORK_STATE",

            "android.permission.GET_ACCOUNTS",
            "android.permission.GET PACKAGESIZE",
            "android.permission.INTERNET",

    };

     */
    public static void requestPermisions(Activity activity) {

        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {                                       // 如果Android的版本小於23, 就跳出requestPermisions()該方法
            return;
        }

        boolean permission = true;

        for (String perm : perms) {
            /** 先判斷是否有權限, 如果沒有權限, 就跳出 然後去申請權限 */
            permission = (activity.checkSelfPermission(perm) == PackageManager.PERMISSION_GRANTED);
            if (!permission) break;
        }

        /** 申请权限  */
        if (!permission) {
            activity.requestPermissions(perms, PERMS_REQUEST_CODE);
        }
    }
}

  3. 最後就是在主頁面, 請求權限  

/** 請求權限 */
Global.requestPermisions(this);
