java - Android 应用程序在启动时崩溃 - SecurityException

Question

当我点击应用程序时不幸的是，应用程序已停止。

我不知道如何解决 Android Studio 中的这个错误，请帮我解决这个问题

这是显示收件箱短信的代码

public class MainActivity extends AppCompatActivity {
ListView lv;
Cursor cr;

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

    dip();
}
public void dip(){
    lv=(ListView)findViewById(R.id.ls);
    ArrayList<String> s;
    s = readAllData();
    String ms="";
    for (int i=0;i<s.size();i++) {
        ms+=s.get(i)+",";
    }
    String messageArray[];
    messageArray=ms.split(",");
    ArrayAdapter<String> adapter = new ArrayAdapter<>(this,android.R.layout.simple_list_item_1,android.R.id.text1,messageArray);
    lv.setAdapter(adapter);
    lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

        }
    });
}
public ArrayList<String> readAllData() {
    ArrayList<String> sms = new ArrayList<>();
    Uri us = Uri.parse("content://sms/inbox");
    cr = getContentResolver().query(us, null, null, null, null);
    assert cr != null;
    cr.moveToFirst();
    while (cr.moveToNext()) {
        String body = cr.getString(cr.getColumnIndexOrThrow("body"));
        sms.add(body);
    }
    return sms;
}

这是 LogCat 异常

Answer 1

您的 logcat 显示 SecurityException，这意味着缺少权限。尝试在 list 中为 com.android.providers.telephony.SmsProvider 设置权限。
