Question

我从getUriForFile方法中遇到异常问题，我在单击Button时尝试捕获图像但是当我执行该操作时应用程序崩溃。

我的日志是：

E/AndroidRuntime: FATAL EXCEPTION: main
              java.lang.IllegalArgumentException: Failed to find configured root that contains /data/data/XXXX/cache/JPEG_20161125_153048_-942097512.jpg

在我的清单文件中，我写了这个：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
        android:maxSdkVersion="18" />
    <provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="XXXX"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths"></meta-data>
    </provider>

file_path.xml

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images" path="Android/data/XXXX/files/Pictures/" />
</paths>

我的onClick方法：

if(v.getId == ...){

Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
photoFile = createImageFile();
photoURI = FileProvider.getUriForFile(this, "com.example.pierre.mycamera", photoFile);
captureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(captureIntent,1);
}

createImageFile：

private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
            imageFileName, /* prefix */
            ".jpg", /* suffix */
            storageDir /* directory */
    );
    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = "file:" + image.getAbsolutePath();
    return image;
}

问题出在哪里？我该如何解决？

提前致谢。
