java - 从画廊或谷歌照片中选择图像失败

Question

编辑:我想更新真正的问题所在。在三星手机上你有“图库”，在“图库”中你还可以看到你的谷歌照片备份。这是我想要得到的照片选择。现在在其他应用程序 (Close5) 上，他们只是显示一条消息，说明 “不支持该照片”。但为什么？为什么我们无法使用此网址 (https://lh3.googleusercontent)？

E/BitmapFactory: Unable to decode stream: java.io.FileNotFoundException: /https:/lh3.googleusercontent.com/-Llgk8Mqk-rI/U8LK0SMnpWI/AAAAAAAAFk4/0cktb59DnL8GgblJ-IJIUBDuP9MQXCBPACHM/I/IMG_20140711_085012.jpg: open failed: ENOENT (No such file or directory)

你们都可以清楚地看到这是一张真实的照片和真实的网址:

https:/lh3.googleusercontent.com/-Llgk8Mqk-rI/U8LK0SMnpWI/AAAAAAAAFk4/0cktb59DnL8GgblJ-IJIUBDuP9MQXCBPACHM/I/IMG_20140711_085012.jpg

一切正常，直到我从照片或谷歌照片图像而不是从画廊中选择，我尝试处理异常(抱歉，不支持该图像。尝试另一个画廊! ) 但这似乎不完整。我试着在这里查看其他解决方案，但没有一个适用于谷歌照片。谢谢!

错误是一个空指针:

Try getPathFromInputStreamUri(), this will fix the content uri problem from google photo app

Kotlin (更新)

fun getPathFromInputStreamUri(context: Context, uri: Uri): String? {
    var filePath: String? = null
    uri.authority?.let {
        try {
            context.contentResolver.openInputStream(uri).use {
                val photoFile: File? = createTemporalFileFrom(it)
                filePath = photoFile?.path
            }
        } catch (e: FileNotFoundException) {
            e.printStackTrace()
        } catch (e: IOException) {
            e.printStackTrace()
        }
    }
    return filePath
}

@Throws(IOException::class)
private fun createTemporalFileFrom(inputStream: InputStream?): File? {
    var targetFile: File? = null
    return if (inputStream == null) targetFile
    else {
        var read: Int
        val buffer = ByteArray(8 * 1024)
        targetFile = createTemporalFile()
        FileOutputStream(targetFile).use { out ->
            while (inputStream.read(buffer).also { read = it } != -1) {
                out.write(buffer, 0, read)
            }
            out.flush()
        }
        targetFile
    }
}

private fun createTemporalFile(): File = File(getDefaultDirectory(), "tempPicture.jpg")

Java

public static String getPathFromInputStreamUri(Context context, Uri uri) {
    InputStream inputStream = null;
    String filePath = null;

    if (uri.getAuthority() != null) {
        try {
            inputStream = context.getContentResolver().openInputStream(uri);
            File photoFile = createTemporalFileFrom(inputStream);

            filePath = photoFile.getPath();

        } catch (FileNotFoundException e) {
            Logger.printStackTrace(e);
        } catch (IOException e) {

                e.printStackTrace();
            }
        }
    }

    return filePath;
}

private static File createTemporalFileFrom(InputStream inputStream) throws IOException {
    File targetFile = null;

    if (inputStream != null) {
        int read;
        byte[] buffer = new byte[8 * 1024];

        targetFile = createTemporalFile();
        OutputStream outputStream = new FileOutputStream(targetFile);

        while ((read = inputStream.read(buffer)) != -1) {
            outputStream.write(buffer, 0, read);

        outputStream.flush();

        try {

        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    return targetFile;

private static File createTemporalFile() {
    return new File(Utils.getDefaultDirectory(), "tempPicture.jpg");
