我正在开发App locker应用程序。如果安装了这个 应用于kitkat版本设备应用程序锁定及其应用 工作完美。最初在棉花糖|（6.0）版本设备中 应用程序正在工作，如果我们重新启动设备应用程序锁定不是 工作，锁定的应用程序打开，不要求任何密码。 如果我们只是输入应用程序（应用程序锁定应用程序）并退出应用程序 工作完美。那个时候它要求密码。

你能帮帮我吗。

检查设备是否是棉花糖并给予权限
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.MARSHMALLOW) {
// only for marshmallow and newer versions
}
答案 1 :(得分：0)
在Android 6.0（MARSHMALLOW）下，它只需要提及清单文件中的所有权限，而在marshmallow及以上版本中，所有权限都由用户授予，因为您需要显示popUp以获取权限。 就像你想使用以下权限一样，然后进行如下编码：
public void checkForMarshmallowPermission() {
for (int i = 0; i < 3; i++) {
switch (i) {
case 0:
isPermissionGiven(Manifest.permission.ACCESS_COARSE_LOCATION, PERMISSION_LOCATION_COARSE);
break;
case 1:
isPermissionGiven(Manifest.permission.ACCESS_FINE_LOCATION, PERMISSION_LOCATION_FINE);
break;
case 2:
isPermissionGiven(Manifest.permission.READ_PHONE_STATE, PERMISSION_READ_PHONE_STATE);
break;
}
}
}
private boolean isPermissionGiven(String permissionName, int requestCode) {
LoggerUtility.e(TAG, "isPermissionGiven :-" + permissionName);
if (ContextCompat.checkSelfPermission(LoginActivity.this,
permissionName)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(YourActivity.this,
new String[]{permissionName},
requestCode);
return false;
}
return true;
}
还覆盖活动中的onRequestPermissionsResult方法：
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
LoggerUtility.e(TAG, "onRequestPermissionsResult :-" + requestCode);
switch (requestCode) {
case PERMISSION_LOCATION_FINE:
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, yay! Do the
// contacts-related task you need to do.
isPermissionGiven(Manifest.permission.READ_PHONE_STATE, PERMISSION_READ_PHONE_STATE);
} else {
// permission denied, boo! Disable the
// functionality that depends on this permission.
}
break;
case PERMISSION_LOCATION_COARSE:
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, yay! Do the
// contacts-related task you need to do.
isPermissionGiven(Manifest.permission.READ_PHONE_STATE, PERMISSION_READ_PHONE_STATE);
} else {
// permission denied, boo! Disable the
// functionality that depends on this permission.
}
break;
case PERMISSION_READ_PHONE_STATE:
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, yay! Do the
// contacts-related task you need to do.
} else {
// permission denied, boo! Disable the
// functionality that depends on this permission.
}
break;
}
}
