Android攝像頭：Android上的setParameters例外

我得到這個錯誤：

Fatal Exception: java.lang.RuntimeException setParameters failed

錯誤日誌表明所有camera.setParameters(parameters)導致崩潰。

這裏是我的代碼：

是你使用虛擬設備還是真實的？ –

我正在使用真實的 – User

而不是使用靜態預覽大小嚐試使用它在API level 5

Camera.Parameters parameters = camera.getParameters(); 
List<Camera.Size> customSizes = parameters.getSupportedPreviewSizes(); 


// Choose desired preview size 
Camera.Size customSize = //Added size 

parameters.setPreviewSize(customSize.width, customSize.height); 
camera.setParameters(parameters); 
camera.startPreview();

推出支持預覽的大小這將是使用這種方法，因爲所有的設備將不支持手動尺寸

更安全的方式

「customSize」的價值是什麼？ – User

@User這將是最適合您的應用程序的預覽大小使用此 'Camera.Size customSize = customSizes.get（0）;' – Anurag

好的謝謝，生病讓你知道，如果它工作！ – User

它大概扔，因爲你正在運行的設備的錯誤/測試。筆者有同樣的問題上QRScanner工作時。

嘗試更改parameters.setPreviewFrameRate（60）;和parameters.setPreviewSize（1920，1080）;根據您使用的設備。快樂編碼
