问题描述

有一段时间我试图让附近基站的CellID和LAC。遗憾的是我没能做到这一点。第一种选择是使用:

For a while I was trying to get CellID and LAC of near base stations. Unfortunately I did not manage to do that. First option was to use:

GsmCellLocation xXx = new GsmCellLocation();
    CID = xXx.getCid();
    LAC = xXx.getLac();
    Toast output = Toast.makeText(getApplicationContext(), "Base station LAC is "+LAC+"\n"
      +"Base station CID is " +CID, Toast.LENGTH_SHORT);
    output.show();

但在这种情况下,我收到值-1(据我所知,这意味着它不是GSM,但是当我检查与isGSM显示真)。另一种方式,我发现网上冲浪(我更新了一点)

But in this case I receive -1 value (as I understand that means it is not a GSM, but when i check with isGSM it shows "true").Another way I have found surfing the net (i updated it a bit)

public void GetID(){
 List<NeighboringCellInfo>  neighCell = null;
 TelephonyManager telManager = ( TelephonyManager )getSystemService(Context.TELEPHONY_SERVICE);
 neighCell = telManager.getNeighboringCellInfo();
 for (int i = 0; i < neighCell.size(); i++) {
 try {
   NeighboringCellInfo thisCell = neighCell.get(i);
   int thisNeighCID = thisCell.getCid();
   int thisNeighRSSI = thisCell.getRssi();
   log(" "+thisNeighCID+" - "+thisNeighRSSI);
 } catch (NumberFormatException e) {
   e.printStackTrace();
   NeighboringCellInfo thisCell = neighCell.get(i);
   log(neighCell.toString());
 }
}
}

但是,在这种情况下,应用程序只是崩溃之后我preSS执行按钮。蚀示出没有错误。可能有人有任何想法如何解决我的问题呢?

But in this case the application just crashes right after I press the execute button. Eclipse shows no errors. May be someone have any ideas how to fix my problems?

LogCat中说:10-05 22:53:27.923:ERROR / dalvikvm(231):无法打开  堆栈跟踪文件/data/anr/traces.txt':权限被拒绝

用于权限:

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_COARSE_UPDATES" />

可能的问题是,我忘了,包括:

May be the problem is that i forgot to include:

TelephonyManager telManager = ( TelephonyManager )getSystemService(Context.TELEPHONY_SERVICE);

更新。我包括从上面排,撞车走了,但现在经过我preSS按钮没有任何反应。更新的源$ C ​​$ C。

Update. I included row from above, crash is gone but now after I press the button nothing happens.Updated source code.

推荐答案

您是否已经验证,你必须在你的清单文件设置正确的权限?

Have you verified that you have the correct permissions set in your manifest file?

TelephonyManager 需要许多具体取决于所使用的API的权限。您需要 READ_PHONE_STATE 对于大多数的API,除了为文档 getNeighboringCellInfo 提到 ACCESS_COARSE_UPDATES ,但是我觉得这可能是一个文档的错误,你真正需要 ACCESS_COARSE_LOCATION 被记录为允许应用程序访问粗(例如,小区ID,无线网络)的位置

The TelephonyManager requires a number of permissions depending on the API you use. You need READ_PHONE_STATE for most of the API's, in addition the documentation for getNeighboringCellInfo mentions ACCESS_COARSE_UPDATES, however I think this may be a doc mistake and you actually need ACCESS_COARSE_LOCATION which is documented as "Allows an application to access coarse (e.g., Cell-ID, WiFi) location"
