Android O使用通知遇到的坑
今天在Android 8.0上使用通知的時候，遇到一個問題，只要一發出通知，就彈出系統介面已停止執行的彈框。如下圖所示
程式碼如下：
NotificationChannel chan1 = new NotificationChannel(PRIMARY_CHANNEL, "cd", NotificationManager.IMPORTANCE_DEFAULT); chan1.setLightColor(Color.GREEN); chan1.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE); notificationManager.createNotificationChannel(chan1); builder = new Notification.Builder(getApplicationContext(), PRIMARY_CHANNEL) .setContentTitle("ds") .setContentText("fa") .setSmallIcon(R.mipmap.ic_launcher) .setAutoCancel(true); notificationManager.notify(NOTI_ID, builder.build());
Log顯示如下：
I/DynamiteModule: Considering local module com.google.android.gms.maps_dynamite:0 and remote module com.google.android.gms.maps_dynamite:19

剛開始根據log在google上搜了半天，沒半點眉目，之後很無奈的一行一行的註釋掉程式碼排除問題所在。結果發現
builder = new Notification.Builder(getApplicationContext(), PRIMARY_CHANNEL) .setContentTitle("ds") .setContentText("fa") .setSmallIcon(R.mipmap.ic_launcher) .setAutoCancel(true);把上面紅色部分註釋掉，正常，取消註釋就崩掉，那麼這就是問題所在了。把圖片複製到drawable-xx資料夾下，
setSmallIcon(R.mipmap.ic_launcher)改為setSmallIcon(R.drawable.ic_launcher)就正常了。雖然問題解決了，但是依然很困惑。drawable和
mipmap在使用上應該是一樣的，只是mipmap在效能上做了優化。希望有知道的能解釋一下
