我的应用程序出现问题,因为我不知道“弹出,发送短信的权限,存储访问权限(将信息存储在手机中)。”
这是我的代码

这是一个简单的例子,在必要时检查Android版本和请求权限:
public void checkAndroidVersion(String phoneNumber){
if (Build.VERSION.SDK_INT >= 23) {
int checkCallPhonePermission = ContextCompat.checkSelfPermission(RegistrationActivity.this,Manifest.permission.SEND_SMS);
if(checkCallPhonePermission != PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(RegistrationActivity.this,new String[]{Manifest.permission.SEND_SMS},SEND_SMS);
return;
}else{
sendSms(phoneNumber);
}
} else {
sendSms(mobile);
}
}
public void sendSms(String phoneNumber)
{
// Your code goes here
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case SEND_SMS:
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
sendSms(phoneNumber);
} else {
Toast.makeText(RegistrationActivity.this, "SEND_SMS Denied", Toast.LENGTH_SHORT)
.show();
}
break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
我希望它有所帮助

试试这个,
private static final int REQUEST = 112;
if (Build.VERSION.SDK_INT >= 23)
{
String[] PERMISSIONS = {android.Manifest.permission.SEND_SMS};
if (!hasPermissions(mContext, PERMISSIONS))
{
ActivityCompat.requestPermissions((Activity) mContext, PERMISSIONS, REQUEST );
} else {
SendSMSMessage();//call send msg function
}
} else
{
SendSMSMessage();//call send msg function
}
获取权限结果
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case REQUEST: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
SendSMSMessage();//call send msg function
} else {
Toast.makeText(mContext, "The app was not allowed to send sms.", Toast.LENGTH_LONG).show();
}
}
}
}
检查marshmallow的权限
private static boolean hasPermissions(Context context, String... permissions) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
return false;
}
}
}
return true;
}
清单
<uses-permission android:name="android.permission.SEND_SMS" />
