Question

在生根并请求超级用户权限后，我需要做什么才能在我的应用程序中启用/禁用gps？

Answer 1

ON Rooted Device尝试使用su来在高精度模式下启用gps

 Process proc=Runtime.getRuntime().exec(new String[]{"su",
"pm grant com.your_app_packagename android.permission.WRITE_SECURE_SETTINGS",
"settings put secure location_providers_allowed gps,network,wifi"});
 proc.waitFor();

在后台线程上运行以下命令：）

Answer 2

您不应该保护用户的隐私。但是通过利用bug可以实现。请参阅以下内容：

How can I enable or disable the GPS programmatically on Android?

请注意，这可能不适用于所有Android版本 - 请参阅
https://android.googlesource.com/platform/packages/apps/Settings/+/4b21f7cd9424eeb83838071a4419912ee5d5e41d

他们表示它已被修复，但我不确定哪个版本有修复（如果有的话）。

此代码适用于 ROOTED 手机，如果应用已移至 /system/aps，并且他们在清单中拥有以下权限：

<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS"/>

private void turnGpsOn (Context context) {
    beforeEnable = Settings.Secure.getString (context.getContentResolver(),
                                              Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
    String newSet = String.format ("%s,%s",
                                   beforeEnable,
                                   LocationManager.GPS_PROVIDER);
    try {
        Settings.Secure.putString (context.getContentResolver(),
                                   Settings.Secure.LOCATION_PROVIDERS_ALLOWED,
                                   newSet); 
    } catch(Exception e) {}
}


private void turnGpsOff (Context context) {
    if (null == beforeEnable) {
        String str = Settings.Secure.getString (context.getContentResolver(),
                                                Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
        if (null == str) {
            str = "";
        } else {                
            String[] list = str.split (",");
            str = "";
            int j = 0;
            for (int i = 0; i < list.length; i++) {
                if (!list[i].equals (LocationManager.GPS_PROVIDER)) {
                    if (j > 0) {
                        str += ",";
                    }
                    str += list[i];
                    j++;
                }
            }
            beforeEnable = str;
        }
    }
    try {
        Settings.Secure.putString (context.getContentResolver(),
                                   Settings.Secure.LOCATION_PROVIDERS_ALLOWED,
                                   beforeEnable);
    } catch(Exception e) {}
}
