1.service超時
【android R】
// How long we wait for a service to finish executing.
static final int SERVICE_TIMEOUT = 20*1000;
// How long we wait for a service to finish executing.
static final int SERVICE_BACKGROUND_TIMEOUT = SERVICE_TIMEOUT * 10;
問題描述：
ANR - executing service com.***.versionUpdateApp/.appupdater.share.UpgradeService
200s bg service超時
Message msg = mAm.mHandler.obtainMessage(
ActivityManagerService.SERVICE_TIMEOUT_MSG);
create/bind/unbind/destoryd等超時20s
后臺service 但是20s就報超時

if (DEBUG_SERVICE) Slog.v(TAG_SERVICE,
"*** startService: " + service + " type=" + resolvedType + " fg=" + requireForeground);
從log來看啟動時fg為false但是還是20s超時原因如下源碼
final boolean callerFg;
if (caller != null) {
final ProcessRecord callerApp = mAm.getRecordForAppLocked(caller);
if (callerApp == null) {
throw new SecurityException(
"Unable to find app for caller " + caller
+ " (pid=" + callingPid
+ ") when starting service " + service);
}
callerFg = callerApp.setSchedGroup != ProcessList.SCHED_GROUP_BACKGROUND;
} else {
callerFg = true;
}
因為caller是fg的狀態(tài)。
