Question

我有一个申请＆＃34; x＆＃34;按钮单击启动服务（在其他一些包中）。此服务现在应该读取呼叫日志并将数据发送到应用程序＆＃34; y＆＃34;应该在SD卡中写入数据。目前，我的服务按下按钮点击，但应用程序＆＃34; y＆＃34;因为我在应用程序中祝酒并且＃34; y＆＃34;它永远不会出现。这些权限用于读取日志，因为我使用自定义操作，因此应用程序的意图过滤器中包含相同的权限＃34; y＆＃34;。有人能说出这个问题的原因。

服务代码

public int onStartCommand(Intent intent, int flags, int startId) {
        Log.d("TAG", "Service started.");
        super.onStartCommand(intent, flags, startId);
        StringBuffer sb = new StringBuffer();
        String strOrder = android.provider.CallLog.Calls.DATE + " DESC";
  /* Query the CallLog Content Provider */
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_CALL_LOG) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return 0;
        }
        Cursor managedCursor = getContentResolver().query(CallLog.Calls.CONTENT_URI, null,
                null, null, strOrder);
        int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER);
        int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE);
        int date = managedCursor.getColumnIndex(CallLog.Calls.DATE);
        int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION);
        sb.append("Call Log :");
        int h = 0;
        while (managedCursor.moveToNext() && h != 20) {
            String phNum = managedCursor.getString(number);
            String callTypeCode = managedCursor.getString(type);
            String strcallDate = managedCursor.getString(date);
            Date callDate = new Date(Long.valueOf(strcallDate));
            String callDuration = managedCursor.getString(duration);
            String callType = null;
            h++;
            int callcode = Integer.parseInt(callTypeCode);
            switch (callcode) {
                case CallLog.Calls.OUTGOING_TYPE:
                    callType = "Outgoing";
                    break;
                case CallLog.Calls.INCOMING_TYPE:
                    callType = "Incoming";
                    break;

            }
            sb.append("\nPhone Number:--- " + phNum + " \nCall Type:--- "
                    + callType + " \nCall Date:--- " + callDate
                    + " \nCall duration in sec :--- " + callDuration);
            sb.append("\n----------------------------------");
        }
        managedCursor.close();
       managedCursor.close();
    Intent sendIntent = new Intent();
    String CUSTOM_ACTION = "com.example.sonali.callreadingservice.CALL_LOGS";
    sendIntent.setAction(CUSTOM_ACTION);
    sendIntent.putExtra(Intent.EXTRA_TEXT, (Serializable) sb);
    sendIntent.setType("text/plain");
    startActivity(sendIntent);
    this.stopSelf();
    return 0;
    }

    @Override
    public void onDestroy() {
        Log.d("slog", "onDestroy()");
        super.onDestroy();
    }

申请＆＃34; y＆＃34;主要活动

``public class MainActivity extends AppCompatActivity {
    TextView textView = null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toast.makeText(this, "Service Started", Toast.LENGTH_SHORT).show();
        textView = (TextView) findViewById(R.id.textview_call);
        Intent intent = getIntent();
        String action = intent.getAction();
        String type = intent.getType();
        handleSendText(intent);

        }


    void handleSendText(Intent intent) {
        String sharedText = intent.getStringExtra(Intent.EXTRA_TEXT);
        try {
            if (sharedText != null) {
                textView.setText(sharedText);
                File sdCard = Environment.getExternalStorageDirectory();
                FileWriter writer = new FileWriter(sdCard);
// Writes the content to the file
                writer.write(sharedText);
                writer.flush();
                writer.close();
            }
        } catch (Exception e) {

        }
    }

应用程序的意图过滤器＆＃34; y＆＃34; `

`<intent-filter>
                <action android:name="com.example.sonali.callreadingservice.CALL_LOGS" />
                <category android:name="android.intent.category.LAUNCHER" />
                <data android:mimeType="text/plain" />
            </intent-filter>

Answer 1

您需要在清单中将自定义操作添加到活动中。

    <activity 
        android:name="MainActivity">
        <intent-filter>
            <action android:name="com.example.sonali.callreadingservice.CALL_LOGS"/>
        </intent-filter>
    </activity>

服务无法启动其他应用的活动
