我認爲，這不是一個缺乏攝像頭權限清單文件，因爲它包含在裏面，除非我試圖喚醒它，否則應用程序工作正常。

我會爲任何一絲真的很高興。

你有兩個？和？ – Fustigador

是的，我已經得到了他們兩個 – sliwkacz

可以請你添加一些更詳細/相關代碼。你瞄準什麼sdk？ –

如果使用的是谷歌Camera2Basic示例應用程序 - issue #42似乎說明問題。解決的辦法是查看您onResume方法的使用在你Fragment - 並呼籲closeCamera()您在onResume()調用openCamera()之前。似乎解決了我的測試Camera2Basic中的問題。

通常情況下，這是因爲你沒有停止攝像設備。我的onPause解決了這個/活動的onResume重寫方法：

@Override 
protected void onResume() { 
    super.onResume(); 
    Log.e(TAG, "onResume"); 
    ... 
    openCamera(); 
    ... 
} 
@Override 
protected void onPause() { 
    Log.e(TAG, "onPause"); 
    closeCamera(); 
    super.onPause(); 
}

這爲我工作。
