Android 7.0+相機、相冊、裁剪適配問題

Android 7.0+相機、相冊、裁剪適配問題

在manifest中：

     <provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="com.***.***.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_paths" />
        </provider>

1、android:authorities：可以隨便取，在之后的代碼需要一一對應：
2、android:resource：創建一個xml文件夾，xml文件夾下創建file_paths資源文件

<?xml version="1.0" encoding="utf-8"?>
<resources  xmlns:android="http://schemas.android.com/apk/res/android">
    <paths>
        <external-path path="" name="camera_photos" />
        <files-path path="" name="photos" />
    </paths>
</resources >

代碼中：

    private String mPhotoPath;
    private Bitmap mBitmap;
    private File mAvatarFile;
    private File fileUri;

 /**
     * 調用手機相機
     */
    private void getImageFromPhoto() {
        File file = new File(Constants.APP_PATH);
        if (!file.exists()) {
            file.mkdirs();
        }
        mPhotoPath = Constants.APP_PATH + String.valueOf(System.currentTimeMillis()) + ".jpg";
        fileUri = new File(mPhotoPath);
        Intent intentCamera = new Intent();
        Uri imageUri;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            imageUri = FileProvider.getUriForFile(ChangeUserInfoActivity.this, "com.***.***.fileprovider", fileUri);
        } else {
            imageUri = Uri.fromFile(fileUri);
        }
        intentCamera.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
        intentCamera.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
        startActivityForResult(intentCamera, START_PHOTO_CAMERA_REQUEST);
