"Settings > Connected Devices > Connection Preferences" 页面的意图

Question

我想知道 AdvancedConnectedDeviceDashboardFragment 的 Intent。在 API 28 上，可以通过以下方式访问此页面：Settings > Connected Devices > Connection Preferences.

This fragment contains all the advanced connection preferences(i.e, Bluetooth, NFC, USB..)

手动交互的logcat：

D/SettingsActivity: Switching to fragment com.android.settings.connecteddevice.AdvancedConnectedDeviceDashboardFragment
D/SubSettings: Launching fragment com.android.settings.connecteddevice.AdvancedConnectedDeviceDashboardFragment

通过 SubSettings 启动它不起作用：

try {
    Intent intent = new Intent();
    intent.setClassName("com.android.settings", "com.android.settings.SubSettings");
    getActivity().startActivity(intent);
} catch (ActivityNotFoundException e) {
    Log.e(LOG_TAG, e.getMessage());
}

因为它没有设置 exported="true" 它给了我：

.SecurityException: Permission Denial: starting Intent { cmp=com.android.settings/.SubSettings (has extras) } from ProcessRecord{75bbdbc 11970:com.acme.application.debug/u0a460} (pid=11970, uid=10460) not exported from uid 1000

是否有机会通过父 SettingsActivity 和 Intent 额外启动它？

Answer 1

在浏览 com.android.settings.Settings 时，我找到了 SettingsActivity 的名称：

ConnectedDeviceDashboardActivity extends SettingsActivity
AdvancedConnectedDeviceActivity extends SettingsActivity

所以我写了一个简单的包装方法，它仍然 throws:

public void showSettings(@NonNull String activityName) throws ActivityNotFoundException {
    Intent intent = new Intent();
    intent.setClassName("com.android.settings", "com.android.settings.Settings$" + activityName);
    getActivity().startActivity(intent);
}

可以这样使用：

try {
    showSettings("AdvancedConnectedDeviceActivity");
} catch (ActivityNotFoundException e) {
    Log.e(LOG_TAG, e.getMessage());
}
