当take photo get - java.lang.Throwable：file：// Uri通过ClipData.Item.getUri（） [英] when take photo get - java.lang.Throwable: file:// Uri exposed through ClipData.Item.getUri()

问题描述

例外是：

file:// Uri exposed through ClipData.Item.getUri()
java.lang.Throwable: file:// Uri exposed through ClipData.Item.getUri()

我的代码在这里：

public static void takePhoto(Fragment fragment, int token, Uri uri) {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (uri != null) {
        intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
    }
    fragment.startActivityForResult(intent, token);
}

我搜索了类似的问题和解决方案。
修改代码如下：

I searched the similar problems and solutions. And modify the code as follow:

public static void takePhoto(Fragment fragment, int token, Uri uri) {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION
            | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
    if (uri != null) {
        intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
        intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
    }
    fragment.startActivityForResult(intent, token);
}

但它也不起作用。

它发生在Android 5.1虽然工作很好在Android 4.3。
有没有人遇到同样的问题吗？
请求一些提前。
正在等待在线...

It happend on Android 5.1 While work well on Android 4.3. Is there anyone meet the same problem? Ask for some advance. Waiting online...

推荐答案

我已经解决了这个问题。

I have already resolved this problem.

首先，发生这个问题是因为 StrictMode 阻止用 file：//

First, this problem occurred because StrictMode prevents passing URIs with a file:// scheme.

因此，有两种解决方案：

So there are two solutions:

1. 更改 StrictMode 。请参见类似问题和其代码。
   但对于我们的应用程序，修改Android源代码是不现实的。

1. Change StrictMode. See similar problem and its code. But for our apps, it is not realistic to modify the Android source code.

使用另一个URI方案，而不是 file：// 。例如，与 MediaStore 相关的 content：// 。

Use another URI scheme, instead of file://. For example, content:// related to MediaStore.

所以我选择了第二种方法：

So I chose the second method:

private void doTakePhoto() {
    try {
        ContentValues values = new ContentValues(1);
        values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpg");
        mCameraTempUri = getActivity().getContentResolver()
                .insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

        takePhoto(this, RequestCode.REQCODE_TAKE_PHOTO, mCameraTempUri);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

public static void takePhoto(Fragment fragment, int token, Uri uri) {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION
        | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
    if (uri != null) {
        intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
        intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
    }
    fragment.startActivityForResult(intent, token);
}

此外，还有另一个解决方案。
