Android線性日曆java.lang.RuntimeException

Question

所以我是Android新手，一直在開發線性日曆的項目。雖然我已經開發了我的代碼，但沒有構建錯誤，但是有運行時錯誤，我不知道如何修復它們。

這裏是我的MainActivity當錯誤出現

public class MainActivity extends Activity { 
private static final String LogTag = "drgn"; 

// TODO move timer thing to view itself 
Handler handler = new Handler(); 
Runnable runnable = new Runnable() { 
    public void run() { 
     contentView.postInvalidate(); 
     handler.postDelayed(runnable, 250); 
    } 
}; 

private TLView contentView; 
private CalStuff calstuff; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    calstuff = new CalStuff(this); 
    setContentView(R.layout.activity_main); 
    contentView= (TLView) findViewById(R.id.fullscreen_content); 

} 
@Override 
protected void onPostCreate(Bundle savedInstanceState) { 
    super.onPostCreate(savedInstanceState); 

    calstuff.LoadCalendars(); 
    Log.d(LogTag, "calendars loaded: " + calstuff.ourCalendars.size()); 

    calstuff.LoadEvents(); 
    Log.d(LogTag, "events loaded: " + calstuff.ourEvents.size()); 

    /* 
    * calstuff.LoadInstances(); Log.d(LogTag, "instances loaded: " + 
    * calstuff.ourInstances.size()); 
    */ 

    contentView.SetCalStuff(calstuff); 
} 

@Override 
protected void onPause() { 
    Log.d(LogTag, "pause"); 
    super.onPause(); 

    handler.removeCallbacks(runnable); 
} 

@Override 
protected void onResume() { 
    Log.d(LogTag, "resume"); 
    super.onResume(); 

    runnable.run(); 
} 

} 

感謝您的幫助提前:)

Answer 1

只是一個想法，但你檢查你的清單文件？正如EWit指出的那樣，類名稱中存在拼寫錯誤（MainActvity vs MainActivity）。我認爲這可能來自您的AndroidManifest.xml文件。

<meta-data 
      android:name="com.google.android.gms.version" 
      android:value="@integer/google_play_services_version" /> 

和硬編碼錯誤google_play_services_version值：包括AndroidManifest與參考時發生
