【问题描述】:
我将我的应用程序上传到 google play,之后我发现我的应用程序并没有在我检查过的所有设备上运行,除了我自己的...
我认为问题是文件保存位置的结果,我使用以下代码:
但是在没有 SD 卡的设备中会发生什么?
在 logcat 中我收到错误“创建目录失败”
// Step 4: Set output file
mMediaRecorder.setOutputFile(getOutputMediaFile(MEDIA_TYPE_VIDEO)
.toString());
outputFileName = getOutputMediaFile(MEDIA_TYPE_VIDEO).toString();
/** Create a File for saving an image or video */
private static File getOutputMediaFile(int type) {
// To be safe, you should check that the SDCard is mounted
// using Environment.getExternalStorageState() before doing this.
File mediaStorageDir = new File(
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MOVIES),
"Your_voice");
// This location works best if you want the created images to be shared
// between applications and persist after your app has been uninstalled.
// Create the storage directory if it does not exist
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
Log.d("Your_voice_App", "failed to create directory");
return null;
}
}
// Create a media file name
String timeStamp = new SimpleDateFormat("ddMMyy_HHmmss")
.format(new Date());
File mediaFile;
if (type == MEDIA_TYPE_VIDEO) {
mediaFile = new File(mediaStorageDir.getPath() + File.separator
+ "Your_voice" + timeStamp + ".mp4");
} else {
return null;
}
return mediaFile;
}
