之前项目对于权限问题的解决方法就是把targetSdkVersion设置为22，而不是25。
对于有强迫症的我，是无法忍受IDE自检出来的黄色警告和提示的，所以直接把targetSdkVersion提到25，compileSdkVersion也提到25，buildToolsVersion也提到25.0.2，v7包，design包也都升到25.3.1。所以随之而来的就要处理对于6.0+的系统的权限适配。
下面是Activity和Fragment中申请权限的代码记录
Activity 以相机和录音权限为例
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA)
!= PackageManager.PERMISSION_GRANTED &&
ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA, Manifest.permission.RECORD_AUDIO}, 0x110);
} else {
//已经获取到权限
//调用接下来的方法
}
} else {
//6.0之下的机器 相当manifest申明了权限几个
//调用接下来的方法
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == 0x110 && grantResults != null && grantResults.length > 0) {
//获取到权限
if (checkPermission(grantResults)) {
//调用接下来的方法
} else {
//用户勾选了不再询问
//提示用户手动打开权限
if (!ActivityCompat.shouldShowRequestPermissionRationale(
this, Manifest.permission.CAMERA)) {
ToastUtils.showShort("相机权限已被禁止，请在应用管理中打开权限");
} else {
ToastUtils.showShort("没有相机权限");
}
if (!ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.RECORD_AUDIO)) {
ToastUtils.showShort("语音权限已被禁止，请在应用管理中打开权限");
} else {
ToastUtils.showShort("没有语音权限");
}
}
}
}
public boolean checkPermission(int[] grantResults) {
if (grantResults == null || grantResults.length == 0) {
return true;
} else {
int temp = 0;
for (int i : grantResults) {
if (i == PackageManager.PERMISSION_GRANTED) {
temp++;
}
}
return temp == grantResults.length;
}
}
Fragment 以相机和录音权限为例
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (ContextCompat.checkSelfPermission((Context) mContext, Manifest.permission.CAMERA)
!= PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{Manifest.permission.CAMERA}, 0x111);
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == 0x110) {
if (grantResults[0] != PackageManager.PERMISSION_GRANTED) {
if (!ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.CAMERA)) {
ToastUtils.showShort("相机权限已被禁止，请在应用管理中打开权限");
} else {
ToastUtils.showShort("没有相机权限");
}
} else {
//调用接下来的方法
}
}
}

补上写的权限工具类
public class PermissionUtils {
/**

public static boolean checkPermission(int[] grantResults) {

return true;

temp++;
}
}
return temp == grantResults.length;
}
}

//用户勾选了不再询问,提示用户手动打开权限
switch (permission) {
case Manifest.permission.CAMERA:
ToastUtils.showShort("相机权限已被禁止，请在应用管理中打开权限");
break;
case Manifest.permission.WRITE_EXTERNAL_STORAGE:
ToastUtils.showShort("文件权限已被禁止，请在应用管理中打开权限");

/**

return false;

for (int i = 0; i < permissionLists.size(); i++) {
temps[i] = permissionLists.get(i);
}
// return permissionLists.toArray(new String[permissionLists.size()]);
return temps;
}
}
Activity中修改为
if (PermissionUtils.checkAndApplyfPermissionActivity(mContext, this,
new String[]{Manifest.permission.CAMERA, Manifest.permission.RECORD_AUDIO, Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUESRCARMEA)) {
livePrecheck();
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == REQUESRCARMEA && grantResults.length > 0) {
//获取到权限
if (PermissionUtils.checkPermission(grantResults)) {
livePrecheck();
} else {
//用户勾选了不再询问
//提示用户手动打开权限
PermissionUtils.showPermissionsToast(this, permissions);
}
}
}
Fragment中修改为
if (PermissionUtils.checkAndApplyfPermissionActivity(mContext, mActivity,
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, IntentExtra.REQUESRALBUM)) {
//获取到权限
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (PermissionUtils.checkPermission(grantResults)) {
switch (requestCode) {
case IntentExtra.REQUESRALBUM:
//获取到权限
break;
}
} else {
PermissionUtils.showPermissionsToast(activity, permissions);
}
}
