Java文件：

java.lang.IllegalArgumentException：找不到配置的root   包含   /storage/emulated/0/Android/data/com.chandan.halo/files/Pictures/JPEG_20170216_233855_-96483920.jpg
     行中的
错误Uri photouURI = ......

BigInteger::BigInteger(std::string str) {
    m_digitCount = str.length();
    m_sizeReserved = m_digitCount;
    m_number = new std::uint8_t[m_sizeReserved];
    std::uint8_t* aArray = new std::uint8_t[m_sizeReserved];
    int j = str.length()-1;
    for(int i=0; i < m_digitCount; i++, j--) {
            aArray[i] = str[j]-'0';
    }
    for(int i=0; i < m_digitCount; i++) {
        m_number[i] = aArray[i];
    }
    delete[] aArray;

}

file_paths.xml

if (photoFile != null) {
                Uri photoURI = FileProvider.getUriForFile(this,
                        "com.chandan.halo.fileprovider",
                        photoFile);
                takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
                startActivityForResult(takePictureIntent, 300);
            }

的manifest.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/com.chandan.halo/Pictures" />
    <!--<external-cache-path name="name" path="path" />-->
</paths>

Answer 1

替换：

<external-path name="my_images" path="Android/data/com.chandan.halo/Pictures" />

使用：

<external-files-path name="my_images" path="Pictures" />
