[英]I cannot seem to run my android studio project on an older android phone
我正在為我的一個大學編碼類（用Java編寫）開發一個游戲項目，並且正在使用Android Studio。 盡管我是Android Studio的新手，但我了解Java基礎知識。 我的主要問題與在較舊的API / SDK版本（尤其是在較舊的手機）上運行/測試我的項目有關。
我一直在開發基於API 26的Android 8.0（Oreo），盡管我也安裝了Pie（API 28）。 當前，我的targetSDKVersion是26，compileSDKVersion是26，而我的minSDKVersion是19。
我正在嘗試在Samsung Galaxy S4（API 19）上運行我的應用程序（稱為AMaze），這就是為什么我的minSDKVersion為19的原因。據我所知，它在支持Android 8.0及更高版本的手機上可以正常運行。 但是，當我在Galaxy S4上運行該應用程序時，它會打開並崩潰，並立即顯示“很遺憾，您的應用程序已停止”。 我不知道如何解決這個問題。
我已經在StackOverflow和Android Developers網站上搜索了答案，但是運氣很小。 我嘗試使用gradle清理和重建項目，嘗試禁用Instant Run，並嘗試使compileSDKVersion 19而不是26（但這會使編譯器感到惱火，說Google Play要求它26歲或以上）。 我假設我的手機與android兼容（請參閱https://developer.android.com/guide/practices/compatibility ），我按照說明將手機連接到計算機（ https://developer.android.com） / training / basics / firstapp / running-app ）。 根據開發者網站，它要做的所有事情就是將minSDKVersion設置為正確的級別，並針對代碼中的所有API棄用和更新進行調整（我認為我已經做到了）。 但這仍然行不通。
我發現的是我的代碼在我的主要活動（稱為AMazeActivity）的onCreate（）方法中產生了膨脹異常。 似乎各種原因都可能導致此錯誤，但我無法找出根本原因。 這個家伙也有類似的情況： android.view.InflateException：二進制XML文件：錯誤誇大類片段
這是在手機上運行應用程序后收到的完整錯誤消息。 錯誤消息說我的膨脹異常是由於試圖使Spinner膨脹：

這是我的主要活動發生崩潰的地方。 我嘗試將代碼放在try / catch塊中，以捕獲異常並將其更干凈地打印出來，如上所示：
@Override
protected void onCreate(Bundle savedInstanceState) {
try {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_amaze);
}
catch (Exception e) {
e.getCause();
Log.e("AMazeActivity", "onCreate", e);
throw e;
}
. . .

注意事項：我在活動中使用了約束布局，在程序中僅使用了一個自定義視圖，並且未使用任何自定義主題。 這是異常抱怨Spinner的XML文件：

android:layout_marginBottom="130dp"
android:entries="@color/colorAccent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
/>
. . .
我認為可能只是更改設置中的幾行（也許在gradle，清單文件，R類，XML文件等中），但是我不知道要更改什么或在哪里更改。 任何幫助將不勝感激！
更改此行
android:entries="@color/colorAccent"
至
android:entries="@array/yourarrayname"
