問題描述

我正在編寫一個應(yīng)用程序，它利用了 android 中的位置模擬可能性.

I am writing an App which makes use of the location mocking possibility in android.

我想要實現(xiàn)的是模擬我的位置，而不在開發(fā)人員選項中設(shè)置允許模擬位置"標志.

What I would like to achive is to mock my location without setting the "allow mock locations" flag in the developer options.

我知道這是可能的，因為它適用于這個應(yīng)用程序:https://play.google.com/store/apps/details?id=com.lexa.fakegps&hl=en

I know that it is possible, because is works with this app: https://play.google.com/store/apps/details?id=com.lexa.fakegps&hl=en

我嘗試了什么:

生成一個 apk，將其移至/system/app，然后重新啟動
而且我還嘗試了在清單中使用和不使用 ACCESS_MOCK_LOCATION 權(quán)限的情況.

Generate an apk, move it to /system/app, do a reboot
And I also tried it with and without the ACCESS_MOCK_LOCATION permission in the manifest.

但這一切都導(dǎo)致了這個例外:
RuntimeException:無法啟動 Activity:SecurityException:需要 ACCESS_MOCK_LOCATION 安全設(shè)置

But it all lead to this exception:
RuntimeException: Unable to start Activity: SecurityException: Requires ACCESS_MOCK_LOCATION secure setting

推薦答案

我已經(jīng)反編譯了你提到的com.lexa.fakegps，它的作用是這樣的:

I have decompiled com.lexa.fakegps you mentioned in question, and what it do like this:

private int setMockLocationSettings() {
    int value = 1;
    try {
        value = Settings.Secure.getInt(getContentResolver(),
                Settings.Secure.ALLOW_MOCK_LOCATION);
        Settings.Secure.putInt(getContentResolver(),
                Settings.Secure.ALLOW_MOCK_LOCATION, 1);
    } catch (Exception e) {
        e.printStackTrace();
    }
    return value;
}

private void restoreMockLocationSettings(int restore_value) {
    try {
        Settings.Secure.putInt(getContentResolver(),
                Settings.Secure.ALLOW_MOCK_LOCATION, restore_value);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

/* every time you mock location, you should use these code */
int value = setMockLocationSettings();//toggle ALLOW_MOCK_LOCATION on
try {
    mLocationManager.setTestProviderLocation(LocationManager.GPS_PROVIDER, fake_location);
} catch (SecurityException e) {
    e.printStackTrace();
} finally {
    restoreMockLocationSettings(value);//toggle ALLOW_MOCK_LOCATION off
}

由于這些代碼的執(zhí)行時間很短，其他應(yīng)用很難檢測到ALLOW_MOCK_LOCATION的變化.

Because the execution time of these code is very short, other apps can hardly detect the change of ALLOW_MOCK_LOCATION.

你也需要，
1. 需要對您的設(shè)備進行 root 訪問
2. 將您的應(yīng)用移動到 /system/app 或 /system/priv-app

我在我的項目中嘗試過，效果很好.

I tried it in my project and it works fine.

這篇關(guān)于使用模擬位置而不在設(shè)置中設(shè)置它的文章就介紹到這了，希望我們推薦的答案對大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
