問(wèn)題:我非常確定我手機(jī)上的app沒(méi)打開(kāi)過(guò),可是應(yīng)用圖標(biāo)都過(guò)年了,他們做到了無(wú)感知更新圖標(biāo),怎么做到的呢?
只有兩種解釋
1. 應(yīng)用市場(chǎng)自動(dòng)更新 手機(jī)設(shè)置里有開(kāi)關(guān)
2. app找到了系統(tǒng)漏洞,可以偷偷執(zhí)行代碼 [這種方案不能說(shuō)沒(méi)有,不予考慮]
動(dòng)態(tài)修改應(yīng)用圖標(biāo)已知方案就是activity-alias.我反編譯了大廠app,京東淘寶沒(méi)找到activity-alias,可是還能無(wú)感知更新應(yīng)用圖標(biāo),無(wú)疑是應(yīng)用市場(chǎng)自動(dòng)更新行為.
京東 沒(méi)有找到activity-alias
淘寶 沒(méi)有找到activity-alias
釘釘 activity-alias方案
網(wǎng)上倒是有activity-alias方案,模板代碼都是你copy我,我copy你,是的我也是抄的,代碼如下[TestActivity,TestActivityShadow 這兩個(gè)activity是我的app入口]
public static void switchAppIcon(boolean isSwich) {
Application context = Utils.getApp();
ComponentName disabletName = new ComponentName(context, TestActivity.class.getName());
ComponentName enableName = new ComponentName(context, TestActivityShadow.class.getName());
if (!isSwich) {
enableName = new ComponentName(context, TestActivity.class.getName());
disabletName = new ComponentName(context, TestActivityShadow.class.getName());
}
PackageManager iPackageManager = context.getPackageManager();
iPackageManager
.setComponentEnabledSetting(disabletName,
PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
PackageManager.DONT_KILL_APP);
iPackageManager
.setComponentEnabledSetting(enableName,
PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
PackageManager.DONT_KILL_APP);
}
activity配置如下所示 activity-alias配置android:exported="true" 必須為true 否則圖標(biāo)更換后打不開(kāi)應(yīng)用[提示未安裝該應(yīng)用(各自機(jī)型可能提示各不相同)]
android:enabled="false" 必須為false 否則桌面顯示多個(gè)圖標(biāo)
<activity
android:name=".TestActivity"
android:exported="true" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity-alias
android:name=".TestActivityShadow"
android:enabled="false"
android:targetActivity=".TestActivity"
android:icon="@mipmap/logo_new"
android:launchMode="singleTop"
android:screenOrientation="portrait"
tools:ignore="IntentFilterExportedReceiver"
android:exported="true" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity-alias>
按照如上配置,執(zhí)行切換圖標(biāo)時(shí)會(huì)出現(xiàn)重啟現(xiàn)象,給activity添加android:launchMode="singleInstance"即可解決
解決重啟現(xiàn)象會(huì)出現(xiàn)另外一個(gè)問(wèn)題,應(yīng)用切換到后臺(tái),在次打開(kāi)app會(huì)重新打開(kāi)啟動(dòng)頁(yè),非期望的運(yùn)行結(jié)果!
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//利用程序安裝器打開(kāi)程序按home回到桌面在點(diǎn)擊圖標(biāo)進(jìn)來(lái)會(huì)導(dǎo)致activity重新創(chuàng)建
if (!isTaskRoot()) {
finish(); // singleInstance后該代碼失效導(dǎo)致
return;
}
}
核心問(wèn)題貌似給activity添加android:launchMode="singleInstance" 能解決重啟問(wèn)題,但是啟動(dòng)頁(yè)又不能加singleInstance,能不能找個(gè)中間過(guò)渡透明的activity,把它弄成singleInstance不就完了.試完了.....嗯~是期望的結(jié)果.打開(kāi)app應(yīng)用圖標(biāo)就變了,姑且叫他無(wú)感知更新應(yīng)用圖標(biāo)!!!示例代碼如下
//啟動(dòng)頁(yè)
public class TestActivity extends AppCompatActivity {
public TestBinding mBinding;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mBinding = DataBindingUtil.setContentView(this, R.layout.activity_test2);
ActivityUtils.startActivity(TansparentActivity.class);
finish();
}
@Override
public void finish() {
super.finish();
overridePendingTransition(0,0);
}
}
//別名activity
public class TestActivityShadow extends FragmentActivity {
}
//中間過(guò)渡activity
public class TansparentActivity extends FragmentActivity {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// 這里寫(xiě)跳轉(zhuǎn)主頁(yè)或者登錄頁(yè)邏輯
ActivityUtils.startActivity(TestRecycleActivity.class);
finish();
}
@Override
public void finish() {
super.finish();
overridePendingTransition(0,0);
}
// 切換圖標(biāo)........
@Override
protected void onDestroy() {
super.onDestroy();
switchAppIcon(true);
}
}
中間過(guò)渡activity配置 注意方向 android:screenOrientation="behind"別寫(xiě)死成android:screenOrientation="portrait" android 8.0會(huì)崩潰
<activity android:name="com.sinochem.seed.apidemos.TansparentActivity"
android:configChanges="keyboardHidden|orientation|screenSize"
android:screenOrientation="behind"
android:theme="@style/AppThemeCompat.Translucent"
android:launchMode="singleInstance"/>
<style name="AppThemeCompat.Translucent" parent="AppTheme">
<item name="android:background">@android:color/transparent</item>
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:colorBackgroundCacheHint">@null</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowContentOverlay">@null</item>
</style>
找到一個(gè)不用中間過(guò)渡的實(shí)現(xiàn)方式 啟動(dòng)頁(yè)onDestory里切換圖標(biāo) 如下代碼啟動(dòng)activity也可以
Intent intent = new Intent(this, TestRecycleActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_DOCUMENT | Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
ActivityUtils.startActivity(intent);
[注意目標(biāo)activity啟動(dòng)模式要非 android:launchMode="singleTask"]
否則請(qǐng)使用中轉(zhuǎn)方式
