Android 6.0 權限問題

因為總總原因,直到現在才重視這個問題

首先根據 官方文件所述
在Android 6.0 (API level 23) 之後分成兩種權限
  • 一般權限(Normal permissions)
  • 危險權限(Dangerous permissions)
列出危險權限的列表
不論一般權限與危險權限,都一樣必須在 AndroidManifest.xml 中使用 <uses-permission> 宣告
而最大的差異在於危險權限必須另外執行請求權限的訊息框

附上在 Activity 實做的儲存權限範例:

...
public final static int PERMISSION_CODE = 1;
protected boolean isStoragePermissionGranted() {
    if (Build.VERSION.SDK_INT >= 23) {
        String permission = android.Manifest.permission.WRITE_EXTERNAL_STORAGE;
        if (PermissionChecker.checkSelfPermission(permission) == PackageManager.PERMISSION_GRANTED) {
            return true;
        } else {
            ActivityCompat.requestPermissions(this, new String[]{permission}, PERMISSION_CODE);
            return false;
        }
    }
    else {
        return true;
    }
}
...
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    switch (requestCode) {
        case PERMISSION_CODE:
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // 成功取得權限後要執行的動作
            } else {
                // 取得權限失敗要執行的動作
            }
            return;
    }
}

呼叫 isStoragePermissionGranted() 時,當需要授權時,就會跳出訊息框詢問。

Android開啟Facebook App

如果手機裡已經安裝了Facebook,為什麼還要開啟瀏覽器重新輸入帳密呢? 直接用Facebook操作不是比較方便呢? --以上是前言--XD 所以為了方便已經安裝Facebook使用者,所以App裡開啟粉絲專頁時,應該會有兩種方式 範例如下: ... public static void openFacebookPage (Context context, String id) { Intent intent = null ; try { context. getPackageManager (). getPackageInfo ( "com.facebook.katana" , 0 ); String uri = "fb://page/" + id; intent = new Intent(Intent. ACTION_VIEW , Uri. parse (uri)); } catch (Exception e) { String uri = "https://www.facebook.com/pages/1/" + id; intent = new Intent(Intent.
