onNewIntent 调用时机
- 需要在清单文件中将启动Activity设置为单任务模式
android:launchmode="singleTask" - 在单任务模式下, 如果是首次创建Activity, 则可以通过getIntent获取传入的Intent, 如果Activity已被创建, 则onNewIntent方法会被调用. 也就是说首次创建不会调onNewIntent方法…
SystemUI显示fileprovider提供的封面图时崩溃
系统日志如下:
注意是SystemUI崩了, 所以只抓自己app的log是抓不到的

是没给systemui授予uri读权限导致的, 详见:
https://github.com/rachel-ylcs/ylcs-kmp/issues/133
https://github.com/PaulWoitaschek/Voice/issues/1860
获取uri后给systemui权限就行, 示例代码如下:
/** * These are necessary to grant the cover uri file permissions. * systemui is related to this one: * https://github.com/PaulWoitaschek/Voice/issues/1860 * * The others are related to watch and car * https://github.com/android/uamp/blob/2136c37bcef54da1ee350fd642fc61a744e86654/common/src/main/res/xml/allowed_media_browser_callers.xml */ listOf( "com.android.systemui", "com.google.android.autosimulator", "com.google.android.carassistant", "com.google.android.googlequicksearchbox", "com.google.android.projection.gearhead", "com.google.android.wearable.app", ).forEach { grantedPackage -> application.grantUriPermission( grantedPackage, uri, Intent.FLAG_GRANT_READ_URI_PERMISSION, ) }
后续的有时间再补充
这玩意为啥能出到第五期的, 谁的问题
