El atributo ro.rk.install_non_market_apps de Android 7.1 no es válido

plataforma

RK3288/RK3368 + Android 7.12

problema

En el SDK anterior, puede establecer el valor predeterminado ro.rk.install_non_market_apps = true para abrir e instalar aplicaciones de fuentes desconocidas de forma predeterminada . Esta propiedad no tiene efecto en el nuevo código

episodio

• El código agregado al principio es:

            loadBooleanSetting(stmt, Settings.Secure.INSTALL_NON_MARKET_APPS,
                        R.bool.def_install_non_market_apps);
            String propNonMarket = android.os.SystemProperties.get("ro.rk.install_non_market_apps");
            if(propNonMarket.equals("true")){
    
    
                loadSetting(stmt, Settings.Secure.INSTALL_NON_MARKET_APPS, "1");
            }

Esto no es válido porque la primera línea de código ha insertado datos en la base de datos. Consulte el siguiente método de asignación de SQLiteStatement :

        SQLiteStatement stmt = null;
        stmt = db.compileStatement("INSERT OR IGNORE INTO secure(name,value)"
                    + " VALUES(?,?);");
