Android 适配6.0 权限检查（PermissionsUtils 相关的辅助类），8.0 ActivieAndroid安全性ContentProvider 问题
前言：最近华为应用市场要求 app targetSkdVersion 要提高到26以及26以上，在期限内可以上架26以下的app ,在期限外就不给上架 等信息，所以直接把app 升到26 （8.0）.
1.适配6.0 权限检查
首先是自己写了一些权限检查的东西，相关流程就 先检查权限，然后根据结果去处理，再重写onRequestPermissionsResult
//第一步检查权限
public static boolean needRequestPerMission(Context context,String persimission){
int checkSelfPermissionWrite = ActivityCompat.checkSelfPermission(context,persimission);
Log.e(TAG, "敏感权限 persimission"+persimission+"检查果 checkSelfPermissionWrite=" + checkSelfPermissionWrite);
return checkSelfPermissionWrite != PackageManager.PERMISSION_GRANTED;
}
//第二步，没有权限的时候，申请权限（单个多个的区别就是 String... permissions 可变数组的问题）
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.CALL_PHONE},
MY_PERMISSIONS_REQUEST_CALL_PHONE);
//第三步，处理用户操作后的后续操作
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
if (requestCode == MY_PERMISSIONS_REQUEST_CALL_PHONE) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
showToast("权限已申请");
} else {
showToast("权限已拒绝");
}
}else if (requestCode == MY_PERMISSIONS_REQUEST_CALL_CAMERA){
for (int i = 0; i < grantResults.length; i++) {
if (grantResults[i] != PackageManager.PERMISSION_GRANTED) {
//判断是否勾选禁止后不再询问
boolean showRequestPermission = ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this, permissions[i]);
if (showRequestPermission) {
showToast("权限未申请");
}
}
}
}
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
发现 还是比较麻烦的，每个activity 都需要写相关的类，重复的代码太多，首先去github 上看有没有相应的框架
目前最流行的运行时权限请求框架PermissionsDispatcher、RxPermissions和easypermissions的使用和对比，看了这篇文章
有三个框架可供选择，最终选了rxJava 的PxPermissions ,简单的封装了下，因为我只需要申请权限后相关的结果，不需要前面一大堆重复的代码

下面是我的辅助类.
public class PermissionsUtils {
private static final String TAG = PermissionsUtils.class.getSimpleName();
public static final String PERMISSION_RECORD_AUDIO = Manifest.permission.RECORD_AUDIO;
public static final String PERMISSION_GET_ACCOUNTS = Manifest.permission.GET_ACCOUNTS;
public static final String PERMISSION_READ_PHONE_STATE = Manifest.permission.READ_PHONE_STATE;
public static final String PERMISSION_CALL_PHONE = Manifest.permission.CALL_PHONE;
public static final String PERMISSION_CAMERA = Manifest.permission.CAMERA;
public static final String PERMISSION_ACCESS_FINE_LOCATION = Manifest.permission.ACCESS_FINE_LOCATION;
public static final String PERMISSION_ACCESS_COARSE_LOCATION = Manifest.permission.ACCESS_COARSE_LOCATION;
public static final String PERMISSION_WRITE_SEIINGS = Manifest.permission.WRITE_SETTINGS;
public static final String PERMISSION_READ_EXTERNAL_STORAGE = Manifest.permission.READ_EXTERNAL_STORAGE;
public static final String PERMISSION_WRITE_EXTERNAL_STORAGE = Manifest.permission.WRITE_EXTERNAL_STORAGE;
public static void requestLocationPermission(final Activity activity, final PermissionsResult result) {
final RxPermissions rxPermissions = new RxPermissions((FragmentActivity) activity);
rxPermissions
.request(PERMISSION_ACCESS_FINE_LOCATION)
.subscribe(new Consumer() {
@Override
public void accept(Boolean aBoolean) throws Exception {
if (result != null) {
result.requestPermissionsResult(aBoolean);
}
}
});
}
public static void checkAndRequestCallPhonePermission(final Activity activity,final String phone){
if(needRequestPerMission(activity,PermissionsUtils.PERMISSION_CALL_PHONE)){
requestPermission(activity, PermissionsUtils.PERMISSION_CALL_PHONE, new PermissionsUtils.PermissionsResult() {
@Override
public void requestPermissionsResult(boolean isAccept) {
if(isAccept){
IntentUtils.toCall(activity, phone);
}else {
Toast.makeText(activity, R.string.no_phone_permission_string,Toast.LENGTH_LONG).show();
}
}
});
}else {
IntentUtils.toCall(activity, phone);
}
}
public static void requestPhonePermission(Activity activity, final PermissionsResult result) {
final RxPermissions rxPermissions = new RxPermissions((FragmentActivity) activity);
rxPermissions
.request(PERMISSION_READ_PHONE_STATE)
.subscribe(new Consumer() {
@Override
public void accept(Boolean aBoolean) throws Exception {
if (result != null) {
result.requestPermissionsResult(aBoolean);
}
}
});
}
public static void requestPermission(Activity activity,String permission, final PermissionsResult result){
final RxPermissions rxPermissions = new RxPermissions((FragmentActivity) activity);
rxPermissions
.request(permission)
.subscribe(new Consumer() {
@Override
public void accept(Boolean aBoolean) throws Exception {
if (result != null) {
result.requestPermissionsResult(aBoolean);
}
}
});
}
/**
* 申请单个或者多个权限,不在乎是否不再询问和哪个权限申请失败，只要有一个失败就执行失败操作：
*/
public static void requestMutlPermission(Activity activity,final PermissionsResult result,String... permissions){
final RxPermissions rxPermissions = new RxPermissions((FragmentActivity) activity);
rxPermissions
.request(permissions)
.subscribe(new Consumer() {
@Override
public void accept(Boolean aBoolean) throws Exception {
if (result != null) {
result.requestPermissionsResult(aBoolean);
}
}
});
}
public static boolean needRequestPerMission(Context context,String persimission){
int checkSelfPermissionWrite = ActivityCompat.checkSelfPermission(context,persimission);
Log.e(TAG, "敏感权限 persimission"+persimission+"检查果 checkSelfPermissionWrite=" + checkSelfPermissionWrite);
return checkSelfPermissionWrite != PackageManager.PERMISSION_GRANTED;
}
//回调出去
public interface PermissionsResult {
void requestPermissionsResult(boolean isAccept);
}

* 6.0权限的基本知识，以下是需要单独申请的权限，共分为9组，每组只要有一个权限申请成功了，就默认整组权限都可以使用了。

* permission:android.permission.READ_CONTACTS

} 相关调用方法；
public void requestCameraPermissions(){
String[] permissionsArray = new String[]{PermissionsUtils.PERMISSION_CAMERA,PermissionsUtils.PERMISSION_READ_EXTERNAL_STORAGE};
if(PermissionsUtils.needRequestPerMission(ContendPublishActivity.this,PermissionsUtils.PERMISSION_CAMERA)
|| PermissionsUtils.needRequestPerMission(ContendPublishActivity.this,PermissionsUtils.PERMISSION_READ_EXTERNAL_STORAGE)){
PermissionsUtils.requestMutlPermission(ContendPublishActivity.this, new PermissionsUtils.PermissionsResult() {
@Override
public void requestPermissionsResult(boolean isAccept) {
if(!isAccept) {
Toast.makeText(ContendPublishActivity.this, R.string.no_camera_permission_string, Toast.LENGTH_SHORT).show();
}else {
PhotoUtils.gotoChooseMulti(ContendPublishActivity.this, MAX_PHOTO_COUNT - photos.size());
}
}
},permissionsArray);
}else {
PhotoUtils.gotoChooseMulti(ContendPublishActivity.this, MAX_PHOTO_COUNT - photos.size());
}
}最后发现现在市场的大多数的app 在启动页面的时候就开始把所有的权限都申请一遍，然后再进入主页，所有也参照了这种处理方式，在需要的地方在进行权限检查即可，有权限就执行，没权限调用辅助类申请。
2.8.0 ActivieAndroid安全性ContentProvider 问题
以前时候了ActiveAndroid 的数据库，然后再8.0手机上面闪退，下面是处理方案
https://github.com/pardom-zz/ActiveAndroid/issues/536#issuecomment-344470558
问题：
解决方案：
注意点：
//这里的name 的自己建的Provider 的路径一定要是自己项目的全路径,
//成功的标示就是能够点入到对应的类即可
//authorities 值对应自己想买的完整的包名
结束语：虽然网上轮子很多，但需要选择自己需要的，还需要进一步的封装，毕竟每个人的需求不一样，不能简单的复制粘贴 还是需要自己手动敲代码和动脑子思考的.
我只是简单的记录了下遇到的问题，最后祝各位 适配顺利，
