相機服務在Android中崩潰
[英]Camera service crashes in Android
問題描述
我正在寫和使用相機的Android應用程序。 活動保存並成像后，另一個活動對其進行處理。 這是保存圖像的活動的代碼

問題是，當我使用此應用程序時，相機服務在兩到三張照片后崩潰，而我的應用程序也隨之崩潰。 它確實保存了一些圖片。 並且在崩潰后，內置的相機應用無法打開。 這是清單：

2 個解決方案
解決方案1

一旦我在真實手機上部署了該應用程序，該錯誤就消失了。 這似乎是模擬器的問題。

嘗試使用此代碼。.i用於消除VM關閉的問題。您可以設置解碼方法，以設置存儲或使用的圖像大小。沒有比這更多的幫助了...
