1.直接调用的方法：
public boolean selfPermissionGranted(String permission) {
// For Android < Android M, self permissions are always granted.
boolean result = true;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (targetSdkVersion >= Build.VERSION_CODES.M) {
// targetSdkVersion >= Android M, we can
// use Context#checkSelfPermission
result = context.checkSelfPermission(permission)
== PackageManager.PERMISSION_GRANTED;
} else {
// targetSdkVersion < Android M, we have to use PermissionChecker
result = PermissionChecker.checkSelfPermission(context, permission)
== PermissionChecker.PERMISSION_GRANTED;
}
}
return result;
}
2.获取Target的方法
try {
final PackageInfo info = context.getPackageManager().getPackageInfo(
context.getPackageName(), 0);
targetSdkVersion = info.applicationInfo.targetSdkVersion;
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
