前段时间要做一个头像选取的功能，本来想使用第三方库，结果在其他的机型好好的，在小米的一个机型上直接崩溃了。
这果断的不能忍啊，咱们自己来实现调用系统相机、相册选取图片的功能，然后进行系统裁剪返回，结果发现刚出一坑又进
入一大坑，下面是填坑指南。
以下代码亲测在小米，华为，oppo等主流机型上兼容，并且兼容android 7.0的 FileProvider。
实现效果：
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
private static final int ACTION_TYPE_PHOTO = 0;
private final int CAMERA = 10;
private final int ALBUM = 20;
private final int CUPREQUEST = 50;
private CircleImageView mCivMainHead;
private PopupWindow mPopupWindow;
private String picPath;
private File mOutImage;
private Uri mImageUri;
private Uri uritempFile;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mCivMainHead = (CircleImageView) findViewById(R.id.civ_main_head);
mCivMainHead.setOnClickListener(this);
//申请权限

ACTION_TYPE_PHOTO,
Manifest.permission.CAMERA,
Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.READ_EXTERNAL_STORAGE);

initPhotoTypePop();
break;

FileProvider 应该在清单文件里进行注册:
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.test.FileProvider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/rc_file_path" />
</provider>
</application>
记得加上权限:
<uses-permission android:name="com.oppo.launcher.permission.READ_SETTINGS" /> <uses-permission android:name="com.oppo.launcher.permission.WRITE_SETTINGS" /> <uses-permission android:name="android.permission.CAMERA"/>
推荐使用mpermission进行运行时权限管理，使用到的第三方库:
//运行时权限 compile 'com.zhy:mpermission-api:1.0.0' //圆形头像 compile 'de.hdodenhof:circleimageview:2.1.0'
