- 判断当前sdk版本
//判断版本
if (Build.VERSION.SDK_INT >= 24) {
imageUri = FileProvider.getUriForFile(MainActivity.this, "com.robert.takepictureandablum.fileprovider", file);
} else {
imageUri = Uri.fromFile(file);
}//启动Activity
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, TAKE_PICTURE);
- 配置provider
在manifest Application节点下加入：
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.robert.takepictureandablum.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_path"/>
</provider>
配置的文件路径，/ 表示是全部文件
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path
name="my_images"
path="/"/>
</paths>
