Question

我正在尝试创建一个按钮，以便将SMS发送到特定号码。但是，即使Android Studio没有问题，按下按钮时应用程序也会在模拟器和物理设备上崩溃。

鉴于AndroidManifest.xml提供了正确的权限，错误没有意义。

有什么想法吗？提前谢谢。

MainActivity.java

package saluta.salutapanicandreporter;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button panicButton = (Button) findViewById(R.id.panicButton);

        panicButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                SmsManager smsManager = SmsManager.getDefault();
                smsManager.sendTextMessage("111-111-111", null, "RED ALERT. Reply SAFE when safe", null, null);
            }
        });
    }
}

的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="saluta.salutapanicandreporter">

    <uses-permission android:name="android.permission.SEND_SMS" />
    <uses-permission android:name="android.permission.READ_SMS" />
    <uses-permission android:name="android.permission.RECEIVE_SMS" />
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        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>

        <receiver android:name=".IncomingSms">
            <intent-filter>
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>

    </application>

</manifest>

Answer 1

你在API＆gt; = 23上进行测试吗？有一个名为“在运行时”的新权限流，你应该使用这个

ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.SEND_SMS}, 1);

检查

已授予的权限

boolean permissionGranted = ContextCompat.checkSelfPermission(this, Manifest.permission.SEND_SMS) == PackageManager.PERMISSION_GRANTED;

另外，我不是舒尔，但是因为KitKat（？）设备上可能只有一个可以发送短信的应用程序（仍有多个可以读取）。你有一个操作系统设置选择器，如浏览器。当你有多个发送短信应用时，他们正在检查（应该......）它们被标记为默认并且能够发送短信。检查这个线索

Answer 2

您可能正在Android M（6）或更高版本上测试您的应用程序？

如果是，则需要运行时权限。

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
{
    // For device above MarshMallow
    boolean permission = getSMSPermission();
    if(permission) {
        // If permission Already Granted
        // Send You SMS here
    }
}
else{
// Send Your SMS. You don't need Run time permission
}


public boolean getWritePermission(){
    boolean hasPermission = (ContextCompat.checkSelfPermission(this, 
    Manifest.permission.SEND_SMS) == PackageManager.PERMISSION_GRANTED);
    if (!hasPermission) {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.SEND_SMS}, 10);
    }
    return hasPermission;
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode)
    {
        case 10: {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
            {
                // Permission is Granted 
                // Send Your SMS here
            }
         }
    }
}

使用SmsManager发送SMS会导致崩溃
