• 需要啟動exported為false的頁面可以使用START_ANY_ACTIVITY權(quán)限螃诅，在AndroidManifeset.xml中直接聲明就可以，當(dāng)然應(yīng)用得有系統(tǒng)簽名的權(quán)限取董，三方簽名的應(yīng)用是沒有該權(quán)限的

• 可以解決SecurityException: Permission Denial異常

java.lang.SecurityException: Permission Denial: starting Intent { flg=0x10000000 cmp=com.chan.test/com.chan.test.activities.MainActivity } from ProcessRecord{168983d 2145:com.chan.test1/u0a15} (pid=2145, uid=10015) not exported from uid 10063
