我的應用程序出現問題：打開時，由於許可證的集成而崩潰。但我不知道問題出在哪裏。請你能幫我找到它嗎？我將非常感激！如何將許可證集成到其Android應用程序中？

請從logcat發佈堆棧跟蹤。 – Simon

很好，謝謝。 – user3152141

我能想到的唯一的事情是，如果你沒有給你的應用程序的權限，它需要運行，但我顯然沒有比你好多哈哈。

謝謝你的回答，不幸的是我已經有了權限^ ^。 – user3152141

我知道這已經有一段時間了，但是如果你或者別人用這種方式遇到了代碼問題，我相當肯定錯誤在哪裏，你準備好讓對話讓它無法使用一個好的許可證迴應。

protected Dialog onCreateDialog(int id) { 

return new AlertDialog.Builder(this)

因爲它是在一個類中它自己的，並注意在課堂

class MainActivity extends Activity

不能使用「本」，因爲AlertDialog.Builder需要一個背景下，你需要像：

protected Dialog onCreateDialog(int id) { 

new AlertDialog.Builder(getApplicationContext())

另一種選擇是做一個公開的上下文變量在MainActivity中，你可以簡單地使用。

class MainActivity extends Activity {

public Context context;

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

然後倒在那裏你創建對話框，你可以使用公共上下文從在MainActivity這樣的：

protected Dialog onCreateDialog(int id) { 

new AlertDialog.Builder(context)

我希望這可以幫助別人，如果它不請投我，這樣我就可以開始提出意見和其他事情。
