我正在学习开发Android移动应用程序。我做了一个简单的应用程序发送短信。我正在使用运行marshmallow的ADB模拟器。我已经阅读了有关新权限here的内容,并且发现了很多问题answers我的问题无法解决。
当我做一个CLEAN和BUILD时,我会收到以下消息:
Error:Gradle: java.io.FileNotFoundException: C:Examples\MySMSApplication\app\build\intermediates\res\resources-debug.ap_ (Access is denied)
注意:我删除uses-permission android:name="android.permission.SEND_SMS
后,我能够成功构建并运行应用。但是,在尝试发送短信说出另一个模拟器号5554时,我将始终收到我的消息Permission denied
。
我的Android清单中设置了两个用户权限。
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.fisher.app">
<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/mysmsapp"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
</application>
</manifest>
然后在mainActivity
中public class MainActivity extends AppCompatActivity {
Button buttonSend;
EditText textPhoneNo;
EditText textSMS;
private static final int PERMISSION_REQUEST = 100;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonSend = (Button) findViewById(R.id.buttonSend);
textPhoneNo = (EditText) findViewById(R.id.editTextPhoneNo);
textSMS = (EditText) findViewById(R.id.editTextSMS);
buttonSend.setOnClickListener(new View.OnClickListener() {
//this is the onclick listener of send button
@Override
public void onClick(View v) {
String phoneNo = textPhoneNo.getText().toString();
String sms = textSMS.getText().toString();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkSelfPermission(Manifest.permission.SEND_SMS) != PackageManager.PERMISSION_GRANTED) {
if (shouldShowRequestPermissionRationale(Manifest.permission.SEND_SMS)) {
Snackbar.make(findViewById(R.id.myView), "You need to grant SEND SMS permission to send sms",
Snackbar.LENGTH_LONG).setAction("OK", new View.OnClickListener() {
@Override
public void onClick(View v) {
requestPermissions(new String[]{Manifest.permission.SEND_SMS}, PERMISSION_REQUEST);
}
}).show();
} else {
requestPermissions(new String[]{Manifest.permission.SEND_SMS}, PERMISSION_REQUEST);
}
} else {
sendSMS(phoneNo, sms);
}
} else {
sendSMS(phoneNo, sms);
}
}
});
}
private void sendSMS(String phoneNo, String message) {
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNo, null, message, null, null);
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Snackbar.make(findViewById(R.id.myView), "Permission Granted",
Snackbar.LENGTH_LONG).show();
sendSMS(textPhoneNo.getText().toString(), textSMS.getText().toString());
} else {
Snackbar.make(findViewById(R.id.MyView), "Permission denied",
Snackbar.LENGTH_LONG).show();
}
}
}
以下是ref:
的Gradle Buildapply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.example.fisher.myapp"
minSdkVersion 23
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.1.1'
}
答案 0 :(得分:0)
好的发现问题不是编译器或整体代码。这是AndroidManifest
我看到和阅读的方式通常是将AndroidManifest.xml中的权限定义为:
<uses-permission android:name="android.permission.SEND_SMS"/>
然而,在稍微阅读了关于影响SDK 23及以上的Marshmallow权限后,我发现它需要:
<uses-permission-sdk-23 android:name="android.permission.SEND_SMS"/>
请注意 -sdk-23 。这样做解决了构建问题,应用示例验证了SEND_SMS权限是否已启用,或者如果没有则请求。
