java.lang.RuntimeException：無法啟動活動

Question

我將我的項目從 Infoscrapper 項目復制到 Infoscrapper2。 之后，我不斷收到運行時異常。 com.example.infoscrapper.CropImageView"無法找到。然而，包 com.example.infoscrapper 不再存在，沒有導入它，也沒有顯式的活動調用。
活動被稱為

public void crop(View v) {
    if (imPhoto.getDrawable() != null) {
        Intent addAdv = new Intent(getApplicationContext(),
                CropImageActivity.class);

        startActivity(addAdv);
    }
}

什么會導致這種行為？

Answer 1

這表明您的 XML 資源文件之一仍然引用舊名稱：

android.view.InflateException: Binary XML file line #35: Error inflating class com.example.infoscrapper.CropImageView

Answer 2

它清楚地表明“ClassNotFoundException”。 檢查您的 apk 文件是否存在 CropImageView 類。 其次做一個干凈的構建並再次創建一個 apk 文件。

Answer 3

嘗試重建項目。 或清理，然后構建。
