如何從相機意圖中獲取URI？

Question

我已經讀過這篇文章： 從android中的相機意圖中獲取uri，但這並沒有幫助我。

為了處理相機請求，我使用了以下代碼：

    public void startCamera() {
    if (PermissionUtils.requestPermission(
            this,
            CAMERA_PERMISSIONS_REQUEST,
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.CAMERA)) {
        //Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
        Uri photoUri = FileProvider.getUriForFile(this, getApplicationContext().getPackageName() + ".provider", getCameraFile());
        intent.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);
        intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        startActivityForResult(intent, CAMERA_IMAGE_REQUEST);
    }
}


 public File getCameraFile() {
    File dir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    return new File(dir, FILE_NAME);
}


    @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == CAMERA_IMAGE_REQUEST && resultCode == RESULT_OK) {
        Uri photoUri = FileProvider.getUriForFile(this, getApplicationContext().getPackageName() + ".provider", getCameraFile());
        uploadImage(photoUri);
    }
}

當我調用函數“ startCamera”時，應用程序崩潰，並在行處給我錯誤：

Uri photoUri = FileProvider.getUriForFile(this, getApplicationContext().getPackageName() + ".provider", getCameraFile());"

有什么幫助嗎？ 謝謝！

通過在“ AndroidManifest”中添加以下內容進行修復 ：

        <provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="${applicationId}.provider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths" />
    </provider>
